This is the eighth in a series of major trigonometry topics, adapted from lessons that I wrote for homeschoolers. It covers the basics of what it means to solve a trigonometric equation as well as the methods of square roots, squaring, factoring (common factor, difference of two squares, trinomials), multiple angles, and finding approximate solutions versus exact solutions. There are many comments with each example building to the next idea. Step-by-step examples and problem solutions. Three to 4 lessons depending on available time.
