Question #25635

I have two questions, both are verifying trigonometric identities, they are:
(secx - tanx)^2 + 1
---------------------- = 2tanx
csc(secx-tanx)
and
1 + cosx + sinx
--------------------- = secx + tanx
1 + cosx - sinx
please show all the steps to reach these two identities, and thank you so much for your help.
