    Undergrad Proving Trig Problem: sec (2x) - 1 = sin^2 x / 2 sec (2x)

    Undergrad Proving Trig Problem: sec (2x) - 1 = sin^2 x / 2 sec (2x)

    [FONT="Courier New"]I'm stuck :/ I have to prove the following: sec (2x) - 1 = sin^2 x ____________ 2 sec (2x) Unfortunately, I don't know any terms that are equal to sec (2x). Any help would be awesome!
