Can someone tell me what I am doing wrong? Thank you.

Prove tanx/(1+cosx) + sinx(1-cosx) = cotx + (secx)(cscx)

I got to the following: see attachment #2

Thanks!

Was anybody able to prove this equation?

I multiplied both sides by (1 + cosx).

Equated tanx to sinx/cosx and cotx to cosx/sinx.

Used the equation sin^2 + cos^2 = 1

And eventually got stuck at (csc^2x)(secx)= -1 - sin^2x ?

Any help appreciated.
