# Plus Two Math's Solution Miscellaneous Chapter2 Inverse Trigonometric Functions

Inverse trigonometry as its name indicates study materials, with inverse trigonometry pdf questions, you can use the inverse trigonometry pdf to do the inverse trigonometry book test, inverse trigonometry notes, and other miscellaneous questions of inverse trigonometry. Proposing a simple technique to solve complex math problems is not an easy task. It requires good knowledge, understanding, and a thorough explanation. This is where the book takes over! Inverse Trigonometry, Math Study Materials is a very important topic in maths for all competitive exams. In this study materials, I have tried to solve all basic questions in inverse trigonometry.

### Chapter  2  Inverse Trigonometric Functions Miscellaneous Exercise

Prove

Consider, $\left&space;(&space;\frac{\sqrt{1+sinx}+\sqrt{1-sinx}&space;}{\sqrt{1+sinx}-\sqrt{1-sinx}}&space;\right&space;)$

Prove

L.H.S = $tan^{-1}\frac{1}{5}+tan^{-1}\frac{1}{7}+tan^{-1}\frac{1}{3}+tan^{-1}\frac{1}{8}$

Prove

test

Prove

Now, we have:

Prove

Using (1) and (2), we have

Solveis equal to

(A)  (B)  (C)  (D)

#### $\theta&space;=tan^{-1}(x)$

$tan^{-1}(x)=\theta$

$tan(\theta&space;)=x$

#### Hence option D

Solveis equal to

(A) (B). (C) (D)

Hence, the correct answer is C.

Find the value of

We know that cos−1 (cos x) = x if, which is the principal value branch of cos −1x.

Here,

Now, can be written as:

Find the value of

We know that tan−1 (tan x) = x if, which is the principal value branch of tan −1x.

Here,

Now, can be written as:

Prove

Now, we have:

Prove

Now, we have:

Prove

Now, we will prove that:

Prove

Let $x=tan^{2}\theta$ Then, $\sqrt{x}=tan\theta$

$\Rightarrow&space;\theta&space;=tan^{-1}\sqrt{x}$

Prove  [Hint: putx = cos 2θ]

Put $x=cos2\Theta$ so that $\theta&space;=\frac{1}{2}cos^{-1}x$, then we have

Solve

Solve

Solvethen x is equal to

(A)  (B)  (C) 0 (D)

Therefore, from equation (1), we have

Put x = sin y. Then, we have:

But, when, it can be observed that:

is not the solution of the given equation.

Thus, x = 0.

Hence, the correct answer is C.
