Question

$If I = \int \frac{d x}{\tan x \log cosec x}, then I equals$

Moderate

A

$\log | \log cosec x | + C$
B

$\log | \log \cos x | + C$
C

$- \log | \log (cosec x) | + C$
D

$None of these$

Solution

$I = - \int \frac{\cot x}{\log \sin x} d x$
$Putting \log \sin x = t, we get I = - \int \frac{d t}{t} = - \log | t | + c$
$∴ I = - l og ∥ \log \sin x ∣ + C$
