Prove the identity:
tanA/secA+1 = secA1/tanA
Can u please explainit to me step by step?
I greatly appreciate your help! Thanks:)

This is exactly like the one with (1sin)/cos
The identity tan^2 = sec^1  1 should help. 
we never learned this identity
at school...is there any basio other identity thtwould help bcz im sure that since we neverlearned this identity in class he wont mark it right on a test..
