    [SOLVED] solutions

    3cos x + 2sin2x=0

    I need to find the solutions in degrees. I know how to use the wave function but this equation has cos x and sin 2x. I normally expect the same quantities of x. I'm not sure if I have studied how to do this.

    I can do it now. It doesn't involve the wave function.
