## Homework Statement

Integrate: cos2x/[cos^2 (x).sin^2 (x)]

## Homework Equations

[/B]

▪cos2x=1-2sin^2 (x)

▪2sinxcosx=sin2x

▪1/sinx = cosecx

▪Integration of cosec^2 (ax+b)=[-cot(ax+b)]/a

▪Integration of sec^2 (x)=tanx

## The Attempt at a Solution

I have attached my solution,but the answer is not matching with the correct answer (written in the last line).I wrote the given answer as well coz it may be a manipulation of my answer,which i can't see(doubtful,but not impossible).If anyone could just point out the line where I'm going wrong..
