I'm having really bad trouble with a few trig identities..if anyone could help that'd be great.
Problem 1 -
2sinx cosx
---------------- = sinx + cosx + 1
sinx + cosx -1
Problem 2 -
sinx - cosx - 1 - cosx + 1
----------------- = ------------
sinx + cosx - 1 sinx
(Note the negative sign in the second fraction can be used for the bottom or the top)
I really appreciate this if anyone can help me out
