Question

$\int \cot^{2} x \cos e c^{4} x d x$

Easy

A

$- \frac{\cot^{3} x}{3} + \frac{\cot^{5} x}{5} + C$
B

$- \frac{\cot^{3} x}{3} - \frac{\cot^{5} x}{5} + C$
C

$- \frac{\tan^{3} x}{3} + \frac{\tan^{5} x}{5} + C$
D

$- \frac{\cot^{3} x}{2} + \frac{\cot^{4} x}{4} + C$

Solution

put $\cot x = t \Rightarrow \cos e c^{2} x d x = - d t$
$\int (- t^{2} - t^{4}) d t = - \frac{t^{3}}{3} - \frac{t^{5}}{5} + C$
