Is there a way to program the HP Prime to understand things like "[1-COS^2(x)/COS^2(x)]" is equal to "TAN(x)"? The HP Prime seems to struggle when it comes to trig identities.
Yes, what that's what I meant. But no, it still just gives back my entry of [COS^2(x)-1]/COS^2(x). Is this a problem with other HP calcs, or is the Prime the only one with a CAS or what? I know the TI nSpire CAS's do fine with trig identities.

HP 50-g returns TAN^2(x) when TRIGTAN is applied to the formula.
