not many people memorize those trig identities, but the rest you should be really familiar with....
I got nailed on cotangent^2/cosecent^3 simplies to what sorta stuff.
ah, I was referring to things like
[tanx]^2 + 1 = [secx]^2, sin2x = 2sinxcosx and those sorts of things.
the one you just cited...you have to be able to nail really quick in science/engineering
cotan^2/cosec^2 = (cos^2/sin^2) / (1/sin^2) = cos^2
EDIT: woops, it was cosec^3, not 2. haha. did the wrong problem
