Solve the equation 3 sin^2 theta = 4 cos theta − 1 for 0 ≤ theta ≤ 360

I would convert the sin squared theta into a cos squared theta using identity that sin sq + cos sq = 1This would then give me a quadratic equation which I would substitute X = cos thetaThen I would solve for XOnce I have solved for X I would equate solution to cos theta and find which angle it is between 0 and 360 degrees.I would do this for all of the solutions of X
