(Sin / 1+sin) + sec^2 = tan sec + 1

please help

What have you figured out so far?

Post the work you've already done and then we can tell you where you went wrong.

What you have written appears to be this:



It is always good with this type of problem to first convert the tan(x) and sec(x) functions into their sin(x) and cos(x) equivalents. Then it's just a matter of combining fractions, and using identities such as cos^2(x) = 1 - sin^2(x). Post back if you're still having difficulty, but show us what you've tried.
