Symbolab Summer Collection or how to symbolab trigonometric equations

When solving trigonometric equations you should be familiar with algebraic manipulations, basic geometry, triangles and more triangles, the six trigonometric ratios, trigonometric identities, trigonometric manipulations, radians, degrees and the unit circle. That’s quite a lot to remember.

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:
