sin^2(x) / 2sin(2x) = cot(x)

The only double angle in that formula is sin(2x) sin(2x) = 0.5*(cosx)(sinx)

Solve the following equation for 0° ≤ θ < 360°. Use the "^" key on the keyboard to indicate an exponent. For example, sin2x would be typed as sin^2x. Be sure to show all your work. 2sin2x - cos2 x - 2 = 0
