To complicate things if there is one solution then there are an infinite number of solutions; trigonometric functions are periodic.

Trying to simplify things, the goal is to isolate the trigonometric function (using the scary list from above). To simplify even more, we are now solving trigonometric equations step by step. Let’s take a look at a few examples:

Example using trigonometric identities (click here):

Example using basic Algebraic manipulations (click here):

Stay tuned, we have more trig coming your way
