    Solving Trig Identities
    I have a test tomorrow and can't solve this question:

    sinxtanx+cosx-secx+1=sec^2xcos^2x

    It helps to put this into simplest terms, so replace all the tan and sec terms with their equivalent sin and cos terms. Then put the left had side over a common denominator of cos(x). You'll see that this complicated-looking equation collapses to a very simple one. Hope this helps.
