Use the equation sin(2x) = 2 sin x cos x so that 6 sinx cosx -2 cosx = 0 cosx*(1 - 3sinx) = 0 (I divided out -2) So the equation is satisfied wherever cosx = 0 or sinx = 1/3 x = pi/2 and 0.3398 radians are two solutions. There are others in other quadrants. Simple and best practice solution for Cos^2x+3sinx-3=0 equation.
