  • This is simply brilliant, you have simplified it very well and made it much easier to understand, sometimes the textbooks use really complex jargon and terminology which confuses people like me. You are an awesome teacher, keep it up.

  • I've skimmed through a couple a few videos on the unit circle before finding yours. Let's just say nothing compares. You speak clearly and precisely, your work is brilliant!

    Your video helped me find some information stored but not used, and this video was the key to unlocking this. I used the unit circle years ago in programming a game but grew up and stored that information away. You've helped me remember it!

    I am trying to program a laser to "plot" a circle...

    On to part 2...

  • I actually understood that! Great job! This is probably the clearest explanation of the unit circle on youtube!!
