Solving Trigonometric Equations with Half-Angles

Additional Resources:

In this lesson, we will continue to learn how to solve trigonometric equations. Here, we will focus on solving trigonometric equations with half-angles. In some cases, these equations can be solved by isolating the trigonometric expression with the half-angle. We can then adjust our domain and find all solutions. Once this is done, we can solve for the unknown and report our solutions. In other cases, we may need to use a half-angle identity and perform a substitution.
