Prove that (secx-cscx)/(secx+cscx)=(tanx-1)/(tanx+1).

Nice example of how to prove a trig identity.

hello. I had that exercise in a math practice but I showed my teacher if it was right and she said no and it was wrong. I am passing trigonometric identities and in 4 days I have an exam. Could you solve that same exercise but on the tangent side, please thank you very much

Did she explain why? Sure, I can solve it going the other way!
