Thread: Verifying Trig Identities

1. Verifying Trig Identities

I need all the work shown. Please help!!! This is due tomorrow

1. secx/sinx-sinx/cosx=cotx

2. cos^4 x - sin^4 x = cos^2 x - sin^2 x

3. tan^2 x/secx-1 = 1+ 1/cosx

4.1+sinx/sinx = cot^2 x/csc x-1

2. If it is due tomorrow, then you would have already attempted these.

Can you show us this work?
