Rewrite it as , expand everything, move to one side and solve the resulting quadratic equation.
Thank you, i didnt think about using the pythagorean identity there
Generally, trigonometric equations with powers are only possible to be solved if you can get it the equation to be only of a single trigonometric function (in this case, the cosine function).
Yeah, i know all of my problems have two trig functions but i have a hard time getting them to only one
