Chapter 2: Q. 36 (page 233)

Find the derivatives of each of the functions in Exercises 17鈥�50. In some cases it may be convenient to do some preliminary algebra.
$f (x) = \ln (x \sin x) .$

Short Answer

Expert verified

The derivative of the given function is: $c o t x + \frac{1}{x} .$

Step by step solution

Step 1. Given Information.

$f (x) = \ln (x \sin x) .$

Step 2. General formulas for finding derivatives.

$\frac{d}{d x} (x^{n}) = n x^{n - 1}, \frac{d}{d x} (\sin x) = \cos x, \frac{d}{d x} (\cos x) = - \sin x, \frac{d}{d x} (\tan x) = s e c^{2} x, \frac{d}{d x} (s e c x) = s e c x \tan x, \frac{d}{d x} (c s c x) = - c s c x c o t x, \frac{d}{d x} (c o t x) = - c s c^{2} x, P r o d u c t r u l e : \frac{d}{d x} (u v) = u \frac{d v}{d x} + v \frac{d u}{d x}, Q u o t i e n t r u l e : \frac{d}{d x} (\frac{u}{v}) = \frac{v \frac{d u}{d x} - u \frac{d v}{d x}}{v^{2}}, C h a i n r u l e : \frac{d}{d x} (f o g (x)) = \frac{d}{d x} (f (g (x))) 脳 \frac{d}{d x} (g (x) .$

Step 3. Solving derivative using above formulas.

$f (x) = \ln (x \sin x), D i f f e r e n t i a t i n g u \sin g c h a i n r u l e w e g e t, \frac{d}{d x} (f (x)) = \frac{1}{x \sin x} \frac{d}{d x} (x \sin x) . \frac{d}{d x} (f (x)) = = \frac{1}{x \sin x} (x \cos x + \sin x) \frac{d}{d x} (f (x)) = \frac{(x \cos x + \sin x)}{x \sin x} = c o t x + \frac{1}{x} .$
