Prove the identity:

tanA/secA+1 = secA-1/tanA

Can u please explainit to me step by step?

I greatly appreciate your help! Thanks:)

• Math -

This is exactly like the one with (1-sin)/cos

The identity tan^2 = sec^1 - 1 should help.

• Math -

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..
