The general solution of the given differential equation, d⁵y/dx⁵ + 5d⁴y/dx⁴ - 2d³y/dx³ - 10d²y/dx² + dy/dx + 5y = 0, involves: solving for the function y(x) that satisfies this equation.

To find the general solution, first, we must determine the characteristic equation associated with the given differential equation. The characteristic equation is:

r^5 + 5r^4 - 2r^3 - 10r^2 + r + 5 = 0.

Solving this equation for the roots r will give us the form of the general solution. The general solution will be a linear combination of the solutions corresponding to each root of the characteristic equation. If the roots are distinct, the general solution will have the form:

y(x) = C₁e^(r₁x) + C₂e^(r₂x) + C₃e^(r₃x) + C₄e^(r₄x) + C₅e^(r₅x),

where C₁, C₂, C₃, C₄, and C₅ are arbitrary constants and r₁, r₂, r₃, r₄, and r₅ are the roots of the characteristic equation. If some roots are repeated, the general solution will involve terms with additional powers of x multiplied by the exponential terms.

The given statement "– = If g(x) = x5, then lim lim g(x) – g(2) = 80. X - 2 x - 2" is False because the limit does not exist.

We have:

g(x) = [tex]x^5[/tex]

g(2) = [tex]2^5[/tex] = 32

We want to evaluate:

lim lim (g(x) - g(2))

x → 2 x - 2

Using algebra, we can rewrite the expression as:

lim lim [tex](x - 2)(x^4 + 2x^3 + 4x^2 + 8x + 16)[/tex]

x → 2 x - 2

We can see that the denominator approaches 0 as x approaches 2, while the numerator approaches a nonzero value. Therefore, the limit does not exist, and the statement is false.

Note that we can also use L'Hôpital's rule to evaluate the limit, which gives the same result:

lim lim (g(x) - g(2))

x → 2 x - 2

= lim lim ([tex]5x^4[/tex])

x → 2 1

= 80

However, this is incorrect, since L'Hôpital's rule can only be used if both the numerator and denominator approach 0 or infinity. In this case, only the denominator approaches 0, while the numerator approaches a nonzero value.

Since the number is not divisible by 2, its units digit must be odd. Since it is not divisible by 3 or 5, the sum of its digits cannot be a multiple of 3 or 5, respectively. This leaves a limited number of possibilities for the digits that add up to 7. One possibility is that the number consists of the digits 1 and 6, which add up to 7 and are not divisible by any of the given numbers. By trying out different combinations of these digits, we can determine that the mystery number is 61.

Therefore, the mystery number that satisfies the given conditions is 61. It is not divisible by 2, 3, 5, or 7, and its digits add up to 7. By analyzing the divisibility and sum conditions, we were able to narrow down the possibilities for the digits and arrive at the solution of 61.

The statistical interpretation of a chi-square value is determined by identifying the p-value associated with it. The p-value represents the probability of obtaining the observed chi-square value or a more extreme value if the null hypothesis is true.

A lower p-value indicates stronger evidence against the null hypothesis, suggesting that the observed data deviates significantly from what would be expected under the null hypothesis. This interpretation helps researchers assess the significance of their findings and make informed decisions about accepting or rejecting the null hypothesis.

In statistical hypothesis testing, the chi-square test is used to determine if there is a significant association between categorical variables. After calculating the chi-square test statistic, which measures the difference between observed and expected frequencies, the next step is to interpret its value. The interpretation is based on the p-value associated with the chi-square value.

The p-value represents the probability of observing a chi-square value as extreme as, or more extreme than, the one calculated, assuming that the null hypothesis is true. The null hypothesis typically assumes that there is no association between the variables being tested. A low p-value indicates strong evidence against the null hypothesis, suggesting that the observed data deviates significantly from what would be expected under the null hypothesis. In this case, researchers reject the null hypothesis in favor of an alternative hypothesis, concluding that there is a significant association between the variables.

Conversely, a high p-value suggests that the observed data is not significantly different from what would be expected under the null hypothesis. In such cases, researchers fail to reject the null hypothesis, indicating that there is not enough evidence to support a significant association between the variables.

By interpreting the p-value associated with the chi-square value, researchers can assess the statistical significance of their findings and make informed decisions about accepting or rejecting the null hypothesis. This allows them to draw conclusions about the relationship between the categorical variables being studied and contribute to the understanding of the underlying phenomenon.

The series converges for -1 < x < 1, and the interval of convergence is:

I = (-1, 1).

To find the radius of convergence, we can use the ratio test:

lim┬(n→∞)⁡|[tex]9(-1)^n n x^{2} /|9 (-1)^n nx^n[/tex]| = lim┬(n→∞)⁡|x|/|1| = |x|

The series converges if the ratio is less than 1 and diverges if it is greater than 1.

So, we need to find the values of x such that |x| < 1:

|x| < 1

Thus, the radius of convergence is R = 1.

To find the interval of convergence, we need to test the endpoints x = -1 and x = 1:

When x = -1, the series becomes:

To evaluate c ∇f · dr, we need to first find the gradient vector ∇f and the differential vector dr.

Since the function f is not given, we cannot find ∇f explicitly. However, we know that ∇f points in the direction of greatest increase of f, and that its magnitude is the rate of change of f in that direction. Therefore, we can make an educated guess about the form of ∇f based on the information given.

The function f could be any function, but let's assume that it is a function of two variables x and y. Then, we have:

∇f = (∂f/∂x, ∂f/∂y)

where ∂f/∂x is the partial derivative of f with respect to x, and ∂f/∂y is the partial derivative of f with respect to y.

Now, let's find the differential vector dr. The parameterization of c is given by:

x = t^2 + 1

y = t^3 + t

0 ≤ t ≤ 1

Taking the differentials of x and y, we get:

dx = 2t dt

dy = 3t^2 + 1 dt

Therefore, the differential vector dr is given by:

dr = (dx, dy) = (2t dt, 3t^2 + 1 dt)

Now, we can evaluate c ∇f · dr as follows:

c ∇f · dr = (c1 ∂f/∂x + c2 ∂f/∂y) (dx/dt, dy/dt)

where c1 and c2 are the coefficients of x and y in the parameterization of c, respectively. In this case, we have:

c1 = 2t

c2 = 3t^2 + 1

Substituting these values, we get:

c ∇f · dr = (2t ∂f/∂x + (3t^2 + 1) ∂f/∂y) (2t dt, 3t^2 + 1 dt)

Now, we need to make an educated guess about the form of f based on the information given. We know that f is a function of x and y, and we could assume that it is a polynomial of some degree. Let's assume that:

f(x, y) = ax^2 + by^3 + cxy + d

where a, b, c, and d are constants to be determined. Then, we have:

∂f/∂x = 2ax + cy

∂f/∂y = 3by^2 + cx

Substituting these values, we get:

c ∇f · dr = [(4at^3 + c(3t^2 + 1)t) dt] + [(9bt^4 + c(2t)(t^3 + t)) dt]

Integrating with respect to t from 0 to 1, we get:

c ∇f · dr = [(4a/4 + c/2) - (a/2)] + [(9b/5 + c/2) - (9b/5)]

Simplifying, we get:

c ∇f · dr = -a/2 + 2c/5

Therefore, the value of c ∇f · dr depends on the constants a and c, which we cannot determine without more information about the function f.

The value of c where c has parametric equations x = t2 + 1, y = t3 + t, 0 t 1. is  c ∇f · dr=  [(2t^5 + 2t^3)(∂f/∂x) + (9t^7 + 3t^5)(∂f/∂y)] dt.

We have the following information:

c(t) = (t^2 + 1)i + (t^3 + t)j, 0 ≤ t ≤ 1

f(x, y) is a scalar function of two variables

We need to find c ∇f · dr.

We start by finding the gradient of f:

∇f = (∂f/∂x)i + (∂f/∂y)j

Then, we evaluate ∇f at the point (x, y) = (t^2 + 1, t^3 + t):

∇f(x, y) = (∂f/∂x)(t^2 + 1)i + (∂f/∂y)(t^3 + t)j

Next, we need to find the differential vector dr = dx i + dy j:

dx = dx/dt dt = 2t dt

dy = dy/dt dt = (3t^2 + 1) dt

dr = (2t)i + (3t^2 + 1)j dt

Now, we can evaluate c ∇f · dr:

c ∇f · dr = [c(t^2 + 1)i + c(t^3 + t)j] · [(∂f/∂x)(2t)i + (∂f/∂y)(3t^2 + 1)j] dt

= [c(t^2 + 1)(∂f/∂x)(2t) + c(t^3 + t)(∂f/∂y)(3t^2 + 1)] dt

= [(t^2 + 1)(2t^3 + 2t)(∂f/∂x) + (t^3 + t)(9t^4 + 3t^2)(∂f/∂y)] dt

Therefore, c ∇f · dr = [(2t^5 + 2t^3)(∂f/∂x) + (9t^7 + 3t^5)(∂f/∂y)] dt.

The solution to the initial value problem ty=1+ te;y(0) = 1 is: y(t) = t - e^(-t)

To solve the initial value problem ty=1+ te;y(0) = 1 using the method of Laplace transforms, we first take the Laplace transform of both sides of the equation: L{ty} = L{1+ te}

Using the property L{t^n f(t)} = (-1)^n F^(n)(s) where F(s) is the Laplace transform of f(t), we can simplify the left-hand side: -L{y'(t)} = -s Y(s) + y(0) Plugging in the initial condition y(0) = 1, we get: -L{y'(t)} = -s Y(s) + 1 Using the Laplace transform of te: L{te} = 1/s^2

Substituting these expressions into the original equation and solving for Y(s), we get: -s Y(s) + 1 = 1/s + 1/s^2 Simplifying this expression, we get: Y(s) = 1/s^2 + 1/s(s-1)

Using partial fractions, we can write this as: Y(s) = 1/s^2 - 1/(s-1) + 1/s Taking the inverse Laplace transform, we get: y(t) = t - e^(-t)

The df for the numerator is k - 1, which represents the number of groups minus one.

The df for the denominator is N - k, which represents the total number of observations minus the number of groups.

In this case, there are 3 groups and each group has n = 19 observations, so the total number of observations is N = 3 x 19 = 57. Therefore:

The df for the numerator is 3 - 1 = 2

The limit of f(x) as x approaches 0 exists and is equal to -47/50 where

[tex]h(x)=−14 {x}^{3} −32{x}^{2}−94{x}^{3}[/tex]

Since g(x) ≤ f(x) ≤ h(x) for -2 ≤ x ≤ 2, we will utilize the squeeze theorem, to discover the constraint of f(x) as x approaches 0.

Agreeing with the press hypothesis, in the event that g(x) ≤ f(x) ≤ h(x) for all x in a few interims containing a constrain point c.

and in case the limits of g(x) and h(x) as x approaches c rise to, at that point, the constrain of f(x) as x approaches c moreover exists and is rise to the common constrain of g(x) and h(x).

In this case, we have:

[tex] - 1 \leqslant \sin( \frac{\pi}{2} {(x)}^{2} ))^{3} \leqslant \frac{ - 1}{4 {x}^{3} } - \frac{3}{2 {x}^{2} } - \frac{47}{50} \\ for - 2[/tex]

Taking the limit as x approaches 0 on both sides of the above inequality, we get:

[tex] - 1 \leqslant lim(x = 0) \sin( \frac{\pi}{2} {(x)}^{2} )^{3} ) \leqslant lim(x = 0)( \frac{ - 1}{4x^{3} - \frac{3}{2 {x}^{3} } }) - \frac{47}{50} [/tex]

The limit on the right-hand side can be found by evaluating each term separately:

[tex]lim(x = 0) \frac{ - 1}{4 {x}^{3} } = 0 \\ lim(x = 0) \frac{ - 3}{2 {x}^{2} } = 0[/tex]

lim (x→0) -47/50 = -47/50

Therefore, the limit of f(x) as x approaches 0 exists and is equal to -47/50:

[tex]lim(x = 0)f(x) = lim(x = 0) \sin( \frac{\pi}{2} ( {x}^{2})^{3} = \frac{ - 47}{50} ) [/tex]

hence, we have shown that the function f(x) defined by g(x) ≤ f(x) ≤ h(x) for -2 ≤ x ≤ 2 approaches a limit of -47/50 as x approaches 0.

Applying the ratio test to this series, we get: | (8^(n+1) / 7^(n+1)) / (8^n / 7^n) | = | (8/7)^n * 8/7 | = (8/7) Since this limit is greater than 1, the series diverges. Therefore, the series 4 (8^n) / 4 (7^n) diverges.

To determine whether the series converges or diverges, consider the given series: 4 * 8^n / (4 * 7^n). First, we can simplify the series by canceling the common factor of 4: (4 * 8^n) / (4 * 7^n) = 8^n / 7^n

Now, rewrite the series as a single exponent: (8/7)^n To determine if this series converges or diverges, we can apply for the Ratio Test.

Since the ratio is constant (8/7), we just need to check if it's less than, equal to, or greater than 1: 8/7 > 1 Since the ratio is greater than 1, the series diverges.

To prove that someone who follows the two rules would live forever, let's analyze the situation.

According to the rules:

(1) Always speak the truth.

(2) Each day, say "I will repeat this sentence tomorrow."

Let's assume that there is a person, let's call them Alice, who follows these rules.

On the first day, Alice says, "I will repeat this sentence tomorrow." Since Alice always speaks the truth, we can trust that she will indeed repeat the sentence the next day.

On the second day, Alice repeats the sentence as promised. Now, on this day, she again says, "I will repeat this sentence tomorrow." According to the rules, she must speak the truth, so we can trust that she will repeat the sentence the following day.

This pattern continues indefinitely. Every day, Alice faithfully repeats the sentence, always speaking the truth.

Now, if Alice were to live forever, she would continue following these rules and repeating the sentence every day. Therefore, it seems that Alice could potentially live forever based on this reasoning.

However, in reality, this scenario cannot work for a few reasons:

1. Mortality: Humans are mortal beings, which means they have a limited lifespan. Regardless of the rules or statements, humans are subject to aging and eventual death. Following the given rules cannot override this fundamental aspect of human existence.

2. Logical Paradox: The statement "I will repeat this sentence tomorrow" leads to a logical paradox. If Alice were to live forever and always repeat the sentence the next day, there would never be a day when the sentence is not repeated.

This creates a contradiction because at some point, the sentence would have to be broken or not repeated, which contradicts the initial statement.

Therefore, while the reasoning may appear valid on the surface, it does not align with the reality of human mortality and leads to logical contradictions. Following these rules cannot guarantee eternal life.

For the expression (1 + b), f(x) = 1 + x and a = 0. Therefore, L(x) = f(0) + f'(0)(x-0) = 1 + x. We have a local maxima at x = -2 and a local minima at x = 2. Since the function y = x^3 - 12x is a cubic function and has no bounds, there are no absolute minima or maxima over the interval (-∞,∞).

The numerical error in the linear approximation is 0 because the linear function is an exact match for the original function.
For y = 3x - x + 6, the differential is dy/dx = 2x + 3. When x = 2 and dx = 0.1, dy/dx = 2(2) + 3 = 7, and the differential is 7(0.1) = 0.7.
To find the local and absolute minima and maxima for y = x - 12x over the interval (-00,00), we take the derivative of y with respect to x: y' = 1 - 12 = -11. The only critical point is at x = 1/12. We evaluate y'' = -11 at x = 1/12 to find that it is a local maximum. There is no absolute maximum or minimum over the given interval.
For the cost function C(x) = x^2 - 1200x + 36,400, we take the derivative with respect to x to find the critical point: C'(x) = 2x - 1200 = 0, which gives x = 600. This is the only critical point. To determine whether it is a minimum or maximum, we evaluate C''(x) = 2 at x = 600. Since C''(600) > 0, we know that x = 600 is a local minimum.
The local and absolute minima and maxima for the function y = x^3 - 12x over the interval (-∞,∞).
1. To find the local minima and maxima, we need to find the critical points of the function. To do this, we first find the first derivative of the function:
y'(x) = d(x^3 - 12x)/dx = 3x^2 - 12
2. Next, set the first derivative equal to zero and solve for x:
3x^2 - 12 = 0
x^2 = 4

x = ±2
3. Now, find the second derivative of the function:
y''(x) = d(3x^2 - 12)/dx = 6x
4. Use the second derivative test to classify the critical points:
y''(-2) = -12 (negative, so it is a local maxima)
y''(2) = 12 (positive, so it is a local minima)
5. Thus, we have a local maxima at x = -2 and a local minima at x = 2. Since the function y = x^3 - 12x is a cubic function and has no bounds, there are no absolute minima or maxima over the interval (-∞,∞).

Therefore, the series converges for all x in the open interval (-1/9, 1/9).

To find the sum of the series for the values of x in this interval, we can use the formula for the sum of an infinite geometric series:

S = a/(1 - r)

where a is the first term and r is the common ratio.

In this case, we have:

a = 9x

The area of the triangle is 98.48. To solve the given triangles, we need to use trigonometric ratios such as sine, cosine, and tangent. Here are the steps for each triangle:

Triangle 1:
Angle A = 30 degrees
Side B = 7
Angle C = 95 degrees

To find side A, we can use the sine ratio:
sin(A)/7 = sin(95)/B
sin(A) = 7(sin(95)/B)
A = sin^-1(7(sin(95)/B))
A = 12.37 degrees

To find side C, we can use the angle sum property:
A + B + C = 180
30 + 95 + C = 180
C = 55 degrees

Now we can find side A using the sine ratio again:
sin(A)/7 = sin(C)/B
sin(A) = 7(sin(C)/B)
A = sin^-1(7(sin(C)/B))
A = 12.37 degrees

Triangle 2:
Side a = 600
Side b = 10
Angle B = 20 degrees

To find angle A, we can use the law of sines:
sin(A)/a = sin(B)/b
sin(A) = (a/b)sin(B)
A = sin^-1((a/b)sin(B))
A = 86.63 degrees

To find angle C, we can use the angle sum property:
A + B + C = 180
86.63 + 20 + C = 180
C = 73.37 degrees

Now we can find the area of triangle I using the formula:
Area = (1/2)ab(sin(C))
Area = (1/2)(600)(10)(sin(10))
Area = 51.51 square units

Triangle 3:
Side a = 10
Angle A = 20 degrees
Side b = 20

To find angle B, we can use the law of sines:
sin(B)/b = sin(A)/a
sin(B) = (b/a)sin(A)
B = sin^-1((b/a)sin(A))
B = 41.81 degrees

To find angle C, we can use the angle sum property:
A + B + C = 180
20 + 41.81 + C = 180
C = 118.19 degrees

Now we can find the area of the triangle using the formula:

For y, the lower bound is 0, and the upper bound is determined by the line connecting the points (-5, 0) and (5, 0). The equation of this line is y = 0, which gives us the upper bound for y.

For x, the lower bound is determined by the line connecting the points (-5, 0) and (0, 5), which has the equation x = -y - 5. The upper bound is determined by the line connecting the points (0, 5) and (5, 0), which has the equation x = y + 5.

Therefore, the integral can be set up as follows:

∬R (2x + 3y)² dA = ∫₀⁵ ∫_{-y-5}^{y+5} (2x + 3y)² dx dy

Now, we can evaluate the integral using these bounds:

∬R (2x + 3y)² dA = ∫₀⁵ ∫_{-y-5}^{y+5} (2x + 3y)² dx dy

                    = ∫₀⁵ [ (2/3)(2x + 3y)³ ]_{-y-5}^{y+5} dy

                    = ∫₀⁵ [ (2/3)((2(y + 5) + 3y)³ - (2(-y - 5) + 3y)³) ] dy

                    = ∫₀⁵ [ (2/3)(5 + 5y)³ - (-5 - 5y)³ ] dy

Evaluating this integral will require further calculation and simplification. Please note that providing the exact answer requires performing the necessary algebraic manipulations.

The head diameters are normally distributed with a mean of 7.1 inches and a standard deviation of 0.8 inches.

Due to financial constraints, the helmets will be designed to fit all men except those with head diameters in the smallest 0.5% or largest 0.5%. To determine the minimum head diameter that will fit the targeted clientele, we can use the z-score formula. A z-score represents the number of standard deviations a data point is from the mean. We'll need to find the z-score that corresponds to the 0.5 percentile (smallest 0.5%) using a standard normal distribution table or calculator. The z-score for the 0.5 percentile is approximately -2.58. We can now plug this z-score into the formula to find the corresponding head diameter:

Head Diameter = Mean + (z-score × Standard Deviation)
Head Diameter = 7.1 + (-2.58 × 0.8)
Head Diameter = 7.1 - 2.064
Head Diameter ≈ 5.036 inches
Therefore, the minimum head diameter that will fit the targeted clientele is approximately 5.036 inches.

The equation of the tangent plane for z = x sinpx ` yq at (1, 1) is z - z₀ = y - 1.

The equation of the tangent plane at a point (x₀, y₀, z₀) on a surface z = f(x, y) is given by:

z - z₀ = fx(x₀, y₀)(x - x₀) + fy(x₀, y₀)(y - y₀)

where fx(x₀, y₀) and fy(x₀, y₀) are partial derivatives of f(x, y) evaluated at (x₀, y₀).

In the given problem, z = x sinpx ` yq and (x₀, y₀) = (1, 1). So,

fx(1, 1) = sinp1 ` 1q = 0

fy(1, 1) = xp1 ` yq = 1

Therefore, the equation of the tangent plane at (1, 1) is given by:

z - z₀ = 0(x - 1) + 1(y - 1)

Simplifying,

z - z₀ = y - 1

Therefore, the equation of the tangent plane for z = x sinpx ` yq at (1, 1) is z - z₀ = y - 1.

Complete Question:

Xavier performs the elementary row operation represented by Ri - R, on matrix A.

To answer the specific question, we need more information about Prob. 4.10, such as the velocity distribution and whether the flow is incompressible.

Once we have this information, we can check continuity and determine if the Navier-Stokes equations are valid. If so, we can determine the pressure distribution by solving the equations for pressure. For the velocity distribution of Prob. 4.10, we need to check continuity to ensure that the flow is physically possible. The continuity equation states that the mass flow rate in a pipe must remain constant, which means that the product of the cross-sectional area and the fluid velocity must remain constant along the pipe. We can check continuity by calculating the mass flow rate at different points in the pipe and comparing them.

To determine if the Navier-Stokes equations are valid, we need to check if the flow is incompressible, which means that the density of the fluid remains constant along the pipe. If the flow is incompressible, the Navier-Stokes equations can be used to describe the fluid motion.

If the flow is incompressible and the Navier-Stokes equations are valid, we can determine the pressure distribution by solving the equations for pressure. We need to know the pressure at a certain point in the pipe to determine the pressure distribution. If we have the pressure at one point, we can use the Bernoulli equation to calculate the pressure at other points along the pipe.

Options 2, 3, and 4 are true for the exponential function f(x) = 3(1/3)^x and its graph.

The following statements are true for the exponential function f(x) = 3(1/3)^x and its graph:

2. The base of the function is 1/3. This is true because the exponential function is of f(x) = a(b)^x,

where "a" is the initial value, "b" is the base, and "x" is the exponent. In this case, "a" is 3 and "b" is 1/3, hence, the base of the function is 1/3.

3. The function shows exponential decay. This is true also, because, the base of the function is < 1. In general, exponential decay occurs when the base of the function is between 0 and 1.

4. The function is a stretch of the function f(x) = (1/3)^x. This is true as well, because, multiplying a function by a constant "a" gives a vertical stretch or compression of the function. In this case, the constant "a" is 3, which gives a vertical stretch of the function f(x) = (1/3)^x by a factor of 3.

Therefore, options 2, 3, and 4 are true for the exponential function f(x) = 3(1/3)^x and its graph.

The critical points we obtain are (±√2, ±√2/2) and we need to check which of these are extrema by plugging them back into f(x, y) = x - y. We find that (±√2, ±√2/2) are saddle points, since f changes sign as we move in different directions.

In the first problem, we are asked to find the extrema of the function f(x-y-z) = x-y+z subject to the constraint x^2 + y^2 + z^2.
To find the extrema, we need to use the method of Lagrange multipliers. We introduce a new variable λ and set up the Lagrangian function L(x,y,z,λ) = f(x,y,z) + λ(g(x,y,z) - c), where g(x,y,z) is the constraint function (x^2 + y^2 + z^2) and c is a constant chosen so that g(x,y,z) - c = 0.
Then we find the partial derivatives of L with respect to x, y, z, and λ, and set them equal to zero to get a system of equations. Solving this system gives us the critical points, which we then plug back into f to determine whether they are maxima, minima, or saddle points.
In this case, we have:
L(x,y,z,λ) = x-y+z + λ(x^2 + y^2 + z^2 - c)
∂L/∂x = 1 + 2λx = 0
∂L/∂y = -1 + 2λy = 0
∂L/∂z = 1 + 2λz = 0
∂L/∂λ = x^2 + y^2 + z^2 - c = 0
Solving for x, y, z, and λ, we get:
x = -1/2λ
y = 1/2λ
z = -1/2λ
x^2 + y^2 + z^2 = c/λ
Substituting these back into f(x-y-z) = x-y+z, we get:
f(x,y,z) = x-y+z = (-1/2λ) - (1/2λ) - (1/2λ) = -3/2λ

To find the extrema, we need to check the sign of λ. If λ > 0, we have a minimum at (-1/2λ, 1/2λ, -1/2λ). If λ < 0, we have a maximum at the same point. If λ = 0, the Lagrangian does not give us any information, and we need to check the boundary of the constraint set.
The constraint x^2 + y^2 + z^2 = c is the equation of a sphere with radius √c centred at the origin. The function f(x-y-z) = x-y+z defines a plane that intersects the sphere in a circle. To find the extrema on this circle, we can use the method of Lagrange multipliers again, setting up the Lagrangian L(x,y,λ) = x-y+z + λ(x^2 + y^2 + z^2 - c) and following the same steps as before.
In the second problem, we are asked to find the extrema of the function f(x, y) = x - y subject to the constraint x^2 - y^2 = 2.  Again, we use the method of Lagrange multipliers, setting up the Lagrangian L(x,y,λ) = x - y + λ(x^2 - y^2 - 2) and solving the system of equations ∂L/∂x = ∂L/∂y = ∂L/∂λ = 0.
