Solving Trig Equations – Part I

*Solving Trig Equations – Part I* covers examples where it is necessary to find a set of angles that solve an equation involving trig functions. We choose to find **all** solutions, not just those on the interval [latex][0, 2\pi)[/latex] to emphasize the periodicity of the solutions. Several examples employ algebraic techniques and students may need to review solving algebraic equations. Further examples involving more complicated angles are saved for *Part II*.
