## Homework Statement

1/1+cosx = csc^2x - cscxcotx

## Homework Equations

## The Attempt at a Solution

R.S= csc^2x - cscxcotx

= (1/sin^2x) - (1/sinx * cosx/sinx)

= (1/sin^2x) - (cosx/sinx^2x)

= 1-cosx / sin^2x

= 1 - cosx / 1 - cos^2x

= 1 / 1 - cos^2x

It does not match the left side and I am unsure of what I did incorrectly.
