WebFeb 1, 2024 · Solve: 3sin^2 x - 2cos^2 x = 4sin x + 7 (0 < x < 2Pi). Solution. Replace in the equation (cos^2 x) by (1 - sin^2 x), then simplify the equation: 3sin^2 x - 2 + 2sin^2 x - 4sin x - 7 = 0. Call sin x = t. The equation becomes: 5t^2 - 4t - 9 = 0. This is a quadratic equation that has 2 real roots: t1 = -1 and t2 = 9/5. WebPythagoras' theorem can also be used to solve 3D problems.
