4.2 The Unit Circle (Pre-Calculus 30)

[@codytheawesome1931]

As a student whose math teacher has no idea what she's doing, these are incredibly helpful.

I can't believe I just spent better part of the last year doing high school upgrading, self-paced, without seeing these videos.
You are a really good human.

I cannot thank you enough for these videos that are so easily and well explained! I have been watching every single one since the start of Pre-Calculus 20 and never even pay attention to my teacher anymore haha. I just watch your videos and it's an easy A! Thanks for making these videos free for all, you really are a great person :)
