    Trigonometry: Simplifying...Please help

    I was wondering if someone could please check my work on these problems. I included each step that I took (it says off to the side which property, etc. that I have used)....the only one that gave me difficulty was 25, which I have skipped...Thank you

    I've looked over all your answers, and if im not mistaken, they all seem to be correct. For number 25... the only thing I could think of is to try and sub in tan^2x + 1 for sec^2x. Im not really sure though.

    That's the easiest way that I see.
