WebIf a triangle can be constructed within a 3-dimensional shape, or over very long distances, then trigonometry can be used. The trick is seeing the triangles, recognizing the important information, and identifying the key formulas to be used. 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.
