In this lesson
Sine, cosine and the unit circle, drawn instead of explained. We build it live in about 14 minutes, then you change it in the Lab until it is yours.
Try this after
Change one number at a time and write down what it did. Most of the good surprises in this course come from the third or fourth change, not the first.
