General Solution of the Equation of form \(a cos\theta\) + \(b sin \theta\) = c

General Solution of the equation \(a cos\theta\) + \(b sin \theta\) = c, where a, b, c \(\in\) R such that | c | \(\le\) \(\sqrt{a^2 + b^2}\). To solve this type of equations, we first reduce them in the form \(cos \theta\) = \(cos \alpha\),  or  \(sin \theta\) = \(sin \alpha\). The following algorithm …
