Explain Solution R.D.Sharma Class 12 Chapter 3 Inverse Trigonometric Function Exercise MCQs Question 38 maths Textbook Solution.

Answers (1)

Answer: $\frac{\sqrt{1-x^{2}}}{x}$

Hint: Try to solve $\sin ^{-1}$ function

Given: $\cot \left(\sin ^{-1} x\right)$

Solution:

Let, $\sin ^{-1} x=\theta$

$\begin{aligned} &\sin \theta=x \\ &\csc \theta=\frac{1}{x} \Rightarrow \csc ^{2} \theta=\frac{1}{x^{2}} \\ &1+\cot ^{2} \theta=\frac{1}{x^{2}} \\ &\cot \theta=\frac{\sqrt{1-x^{2}}}{x} \end{aligned}$
