WebSolving trigonometric equations requires the same techniques as solving algebraic equations. We read the equation from left to right, horizontally, like a sentence. ... Use a … WebJun 14, 2015 · For equation (1), make the substitution cos θ r = ± 1 − sin 2 θ r and multiply through by sin θ r to get. e − m t sin θ r = ± 1 − sin 2 θ r. Squaring both sides and setting equal to zero, we get. ( m t 2 + 1) sin 2 θ r − 2 e m t sin θ r + ( e 2 − 1) = 0. Solving for sin θ r using the Quadratic Formula gives.

WebThis trigonometry video provides a basic introduction into solving trigonometric equations. it explains how to find all solutions by representing the soluti... WebSolving for all possible values of t means that solutions include angles beyond the period of 2π. Solving for t on the unit circle, we can see that the solutions are t = π 6 and t = 5π 6. But the problem is asking for all possible values that solve the equation. Therefore, the answer is. t = π 6 ± 2πk and t = 5π 6 + 2πk.
