Find the exact solutions of the given equation in the interval [0,2π]: sin^2x + sin2x = -cos^2x + 1 OpenStudy (jamesj):

well, first of all, remember that $\sin^2 x + \cos^2 x = 1$ Use that to simplify your problem! OpenStudy (mertsj):

$\sin ^2x+\sin 2x+\cos ^2x-1=0$ $1+\sin 2x-1=0$ $\sin 2x=0$ OpenStudy (mertsj):

Take it from there. OpenStudy (anonymous):

ok, i will give it a try OpenStudy (anonymous):

i know that 0 would work for a solution, but what is the best way to find the rest of the choices? OpenStudy (anonymous):
