Solving trig equations is just finding the solutions of equations like we did with linear, quadratic, and radical equations, but using trig functions instead. We will mainly use
the
Unit Circle
to find the exact solutions if we can, and we’ll start out by finding the solutions from \(\left[ 0,2\pi \right)\).
We can also solve these using a Graphing Calculator, as we’ll see
