Typical is to let u = arctan(A / B) (dealing with the special case of B = 0 separately), r = √A2 + B2. Then A = rsinu B = rcosu (unless I've swapped those two). Now your equation reads rsinusinθ + rcosucosθ = C which you rewrite as cos(u − θ) = C r θ = u − arccos(C r) and you're done.

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.
