Chapter 2: Q. 42 (page 233)

Find the derivatives of each of the functions in Exercises 17–50. In some cases it may be convenient to do some preliminary algebra
$f (x) = \sin (\sin^{- 1} x)$ .

Short Answer

Expert verified

The derivative is $1 .$

Step by step solution

Step 1. Given Information.

The given function is $f (x) = \sin (\sin^{- 1} x)$ .

Step 2. Preliminary Algebra.

We know,

$\frac{d}{d x} (\sin x) = \cos x \frac{d}{d x} (\sin^{- 1} x) = \frac{1}{\sqrt{1 - x^{2}}} (f g)^{'} (x) = f^{'} (x) g (x) + f (x) g^{'} (x)$

Step 3. Derivative of the function.

The derivative of the function will be,

$\frac{d}{d x} (\sin (\sin^{- 1} x)) = \frac{d}{d x} (x) S i n c e, [\sin^{- 1} x is the inverse of \sin x] T h e r e f o r e, \frac{d}{d x} (\sin (\sin^{- 1} x)) = 1$
