WebTrigonometric Equations. To solve a trigonometric equation, we need the following preliminary knowledge: \theta=n\pi+ (-1)^ {n}\alpha θ = nπ+ (−1)nα. Thus, if. \theta=2m\pi+\alpha θ = 2mπ +α. \theta = 2n\pi\pm\alpha θ = 2nπ ±α. \theta=n\pi+\alpha θ = nπ+ α. These hold true for integers n,m n,m. Now on to solving equations. 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 …
