1. The problem statement, all variables and given/known data I need to write a function of theta in terms of a particular variable. I just can't seem to figure it out; the only solution I can come up with is when the aforementioned variable is equal to 0 or 1. I'm using Q to denote theta, and b is the variable. sin^3(Q)/cos(Q)=b^2 2. Relevant equations Any and all trig identities. I've used sin^2(x)+cos^(x)=1, sin(2x)=2sin(x)cos(x), I haven't stumbled into any work that led me to use other identities! 3. The attempt at a solution Around 5 pages of scratch work, all for naught. Any relevant trig identities I might be missing would be nice to know, if anyone figures this out soon! Thanks!
