Question

If I = $\int sec ^4x \, cosec ^2x \,dx$ =K tan ^3x +L tan x+M cot x + const, then

A

$K= \frac {1}{3}$ L = 1,M = 2

B

$K= \frac {1}{3}$ L = 2,M = -1

C

K = - 1, L = 0, M = 1

D

none of these

Answer

$K= \frac {1}{3}$ L = 2,M = -1

Explanation

Solution

Answer (b) $K= \frac {1}{3}$ L = 2,M = -1
