Chapter 2: Q 24. (page 222)

Find the derivatives of the functions: $f (x) = \frac{e^{x} \ln x}{x^{2} - 1}$

Short Answer

Expert verified

The required answer is $\frac{(x^{2} - 1) (e^{x} \frac{1}{x} + e^{x} \ln x) + 2 x e^{x} \ln x}{{(x^{2} - 1)}^{2}}$ .

Step by step solution

Step 1. Given information.

The given function is: $f (x) = \frac{e^{x} \ln x}{x^{2} - 1}$

Step 2. Find the derivative of the given function.

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