ALso by any chance can you help me solve 1+sec^2xsin^2x=2x

We have strict forum basics for assisting with homework questions. Sorry, but we can't help you solve your problem.

As Tickle said, you really should ask this on the "education" forum.

Nevertheless, I can provide a little bit of guidance:

Keep in mind that it's easy to factor the difference of two squares (a^2-b^2=(a+b)(a-b). Now notice that \sin ^2 x and 1 are both perfect squares.

So once you factor the numerator, do you find any factors that cancel in the denominator?
