The value of

\int \frac{\cos x}{\sin ^2 x(\sin x+\cos x)} d x

is equal to

View answer and explanation

Correct option: A

\log \left|\frac{1+\tan x}{\tan x}\right|-\cot x+C

Option A (

\log \left|\frac{{1+\tan x}}{{\tan x}}\right|-\cot x+C

) is correct because the integral can be solved by dividing the numerator and denominator by cos³(x) and using partial fractions after substituting tan(x) = t.
