d/d{cosec^-1(1+x²/2x)} is equal to
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
Let assume that
[tex]\rm :\longmapsto\:y = {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
We know,
[tex]\boxed{\tt{ {cosec}^{ - 1}x = {sin}^{ - 1}\bigg( \dfrac{1}{x} \bigg)}}[/tex]
So, using this, we get
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2x}{1 + {x}^{2} } \bigg)[/tex]
Now, we use Method of Substitution, So we substitute
[tex] \red{\rm :\longmapsto\:x = tanz \: \rm\implies \:z = {tan}^{ - 1}x}[/tex]
So, above expression can be rewritten as
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2tanz}{1 + {tan}^{2} z} \bigg)[/tex]
[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( sin2z \bigg)[/tex]
[tex]\rm\implies \:y = 2z[/tex]
[tex]\bf\implies \:y = 2 {tan}^{ - 1}x[/tex]
So,
[tex]\bf\implies \: {cosec}^{ - 1}\bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = 2 {tan}^{ - 1}x[/tex]
Thus,
[tex]\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]
[tex]\rm \: = \: \dfrac{d}{dx}(2 {tan}^{ - 1}x)[/tex]
[tex]\rm \: = \: 2 \: \dfrac{d}{dx}( {tan}^{ - 1}x)[/tex]
[tex]\rm \: = \: 2 \times \dfrac{1}{1 + {x}^{2} } [/tex]
[tex]\rm \: = \: \dfrac{2}{1 + {x}^{2} } [/tex]
Hence,
[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ \dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = \frac{2}{1 + {x}^{2} }}}}[/tex]
Hence, Option (d) is correct.

Answer:
A
Step-by-step explanation:
you just follow the trail
Answer:
A - 2
Step-by-step explanation:
It can't be B or D, because the other triangle is bigger than the first one.
It is not 4 because if you count the squares, you will notice that b=2 and a=4. So the scale factor is 2.

Simplify 11 square root 1215
Answer:
35
Step-by-step explanation:
Its 34.85685 but simplifies to 35.
Answer:
[tex]99\sqrt{15} \thickapprox \:383.42535[/tex]
Step-by-step explanation:
[tex]11\sqrt{1215}[/tex]
Factor [tex]1215[/tex] [tex]=9^{2} \times 15[/tex]. Rewrite the square root of the product [tex]\sqrt{9^{2} } \sqrt{15}[/tex], than take the square root of [tex]9^{2}[/tex].
[tex]11\times 9\sqrt{15}[/tex]
Multiply 11 and 9 which will give you 99.

Giải phương trình:
sin*2x+sinxx.cox=1/2
Answer:
x = 9.47 degrees ( in first quadrant.
Step-by-step explanation:
sin2x + sinx cos x = 1/2
Now sinx cos x = 1/2sin2x so:
3/2sin2x = 1/2
sin2x = 1/2 / 3/2
sin2x = 1/2 * 2/3 = 1/3
2x = arcsin 1/3 = 19.47 degrees
x = 9.74 degrees to nearest hundredth.
