Learn how to solve Trigonometric Equations without the use of a calculator
Trigonometric equations come in various shapes and sizes. Additionally, some require a calculator while others don’t, and some are in degrees and others radians. If the calculator isn’t allowed then you must use trigonometric exact values to find the solutions. The key with these equations is to categorise them and then apply the correct technique. In this video I show you how to solve trig equations using exact values. I start by reviewing exact values and then move onto the equations themselves.
