    (sec(x)-tan(x))^2
    How would you simplify the equation (sec(x) - tan(x))^2 ? I have tried a few different ways and all I seem to end up with is a jumbled mess of equations. I just can't seem to see this one. Thanks in advance for any help.

    Well, you could start by converting everything to the basic trig ratios; sin and cos. You'll get two fractions. Combine them and apply the square; don't expand yet.

    Then convert everything to sine. Maybe that should show you the next step :)
