# Math Help - Trig Identities - Proof

1. ## Trig Identities - Proof

2+(sin^2x/cos^2x)?

I'm not good with fractions.

2. The title says Trig Identities - Proof. What are you trying to prove?

why use fractions at all ?

$2 + \frac{\sin^2{x}}{\cos^2{x}} = 2 + \tan^2{x} = 1 + \sec^2{x}$

4. the original equation is ((2+ tan^2x)/(sec^2x)) -1

that is not an equation ... what is it equal to ?

in future, please post the entire problem from the start ... as it is, I have no idea what you are trying to do.
