# Trig Identity Simplification

## Homework Statement

Simplify the following:

(1/cos2θ) - (1/cot2θ)

## Homework Equations

Various trig identities

## The Attempt at a Solution

I tried to make cos2θ into 1-sin2θ and cot2θ into csc2θ-1 but still couldn't find any obvious solution. Help?

What do you get if you express cot as something using sines and cosines?? What if you then add up the fractions?

Did you try simply inverting both fractions? Does that show similarity to a trigonometric identity that you know?
