TL;DR

Tutorial on finding coterminal angles between 0 and 360 degrees, including computations and explanations.

Transcript

okay I'm gonna show you guys how to find it please pass the coterminal angles to this to keep an angles and as we can see these two angles they are not between of 0 and 360 degrees right that means the answers yet they will be in between of 0 and 360 degrees so keep that in mind and also in this video I'll just show you guys how to do the computati...
