Question 1024158: For all the values of theta for which the expressions are defined, prove the following is an identity: (cos theta sin theta+cos theta)/cos^2theta=tan theta +sec theta
I don't quite understand how to prove it is an identity.

Prove that you can go from the left side and derive the right side or vice versa.

True for all values of theta, so the original statement is also true for all values of theta.
