Homework Help: Trig

Posted by Andrea on Thursday, February 28, 2008 at 5:01pm.

Verify that each of the following is an identity.


I can get it down to cos^2 on the right, but cannot get it to work out on the left.

secx/cosx - tanx/cotx=1

On the left I got down to 1-tan^2, but that clearly doesn't equal 1....


I'm really not sure where to go with this one. Any help would be appreciated. Thanks in advance.
