Equations involving a single trigonometric function can be solved or verified using the unit circle. We can also solve trigonometric equations using a graphing calculator. Many equations appear quadratic in form. We can use substitution to make the equation appear simpler, and then use the same tec...
This lesson will provide examples and explain how to solve trigonometric functions while applying this knowledge to solve trigonometric equations.
