I am having issues. This is the only one I am having issues with proving.

Prove this is an identity

tan v      sin v              tan v  -  sin v

______________  =  _______________

tan v  +  sin v             tan v      sin v

It also wants me to prove graphically it is an identity, but I would settle on help with proving algebraically.

Hell if I know I have never done a problem like that. But I do know when you have a positive and negative on the opposite side they cancel out. That would leave the two top/bottom without signs there by themselves.

This is a Trig Identity, basically I have to prove the trig identity on one side of the = is equal to the other side using the Pythagorean Identities.

I regret taking this class. It is going to ruin my Dean's list status.

I would be happy to help (I have fun with math questions) if my kids would let me think tonight
