Hey Melcarthus. Your equation is wrong. As an example let theta = 0, then on the LHS you get 0/0 for the answer but on the RHS you get 1/1. The equation is screwed up.
Hello, Melcarthus! The left side is: . Then: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Hi Melcartus, a alternative solution: (sint-cost+1)*cost=(sint+cost-1)*(sint+1) You receive a identity, not forget, that sin^2(t)+cos^2(t)=1.
