How to solve for sine theta
WebMay 20, 2015 · Whenever sin (theta) = -1, we get cos (theta) = +-sqrt (1-sin^2theta) = 0 and cos (theta)-sin (theta) = 0 - (-1) = 1. sin (theta) = -1 for theta = -pi/2+2npi for all n in ZZ. Putting two cases together, we have solutions when: theta = 2npi for all n in ZZ and when theta = -pi/2 + 2npi for all n in ZZ To make sure that these are the only solutions: WebNov 2, 2024 · a ⋅ sin ( θ) + b ⋅ cos ( θ) = A sin ( θ + τ) = A ⋅ sin ( θ) cos ( τ) + A ⋅ cos ( θ) sin ( τ) You can express tan ( θ + τ) using cos ( θ + τ) = − + 1 − sin 2 ( θ + τ). You will get the result …
