Question 816078: verify the identity by showing that the left equals right sec^2x/1-tan^2=sec2x
do I use 1/cos^2x/1-tan^2x or do I use 1+tan^2x/1-tan^2x? either way I do not know where to go from either one of those this is really confusing to me and I just cannot get it.

verify the identity by showing that the left equals right
sec^2x/1-tan^2=sec2x
***
sec%5E2%28x%29%2F%281-tan%5E2%28x%29%29=sec%5E2%28x%29
start with left side:
sec%5E2%28x%29%2F%281-tan%5E2%28x%29%29
..

..
verified: left side=right side
