How would you show that one trigonometric expression is equal to another? I’m not exactly sure how to start.

  1. start by using the most basic identities:
    tanx=sinx/cosx
    sin^2x + cos^2x = 1

    by dividing by cos^2x you get

    tan^2x+1 = sec^2x

    divide by sin^2x and you get

    1+cot^2x = csc^2x

    There should be a section in your text covering trig identities. It will start out with simple ones like these and move on to more complicated ones.
