Q 40. Find the derivatives of each of ... [FREE SOLUTION]

Chapter 2: Q 40. (page 222)

Find the derivatives of each of functions in Exercises 17鈥�44. In some cases it may be convenient to do some preliminary algebra.
$f (x) = \ln (x^{2} + 1) {(e^{x})}^{- \frac{1}{3}}$

Short Answer

Expert verified

The required answer is $f' (x) = - \frac{1}{3} e^{x} \ln (x^{2} + 1) + {(e^{x})}^{- \frac{1}{3}} 路 \frac{2 x}{x^{2} + 1}$

Step by step solution

Step 1. Given information.

The given function is:

$f (x) = \ln (x^{2} + 1) {(e^{x})}^{- \frac{1}{3}}$

Step 2. Find the derivative of the given function.

$f (x) = \ln (x^{2} + 1) {(e^{x})}^{- \frac{1}{3}} f' (x) = \frac{d}{d x} (\ln (x^{2} + 1) {(e^{x})}^{- \frac{1}{3}}) = - \frac{1}{3} e^{x} \ln (x^{2} + 1) + {(e^{x})}^{- \frac{1}{3}} 路 \frac{1}{x^{2} + 1} 路 2 x = - \frac{1}{3} e^{x} \ln (x^{2} + 1) + {(e^{x})}^{- \frac{1}{3}} 路 \frac{2 x}{x^{2} + 1}$
