@CmonMattTHINK Then the angle v. y-values of the points on the circle for each challenge gives transformed sine curves.
I.e. to moves the points twice as fast, we have to double our inputs (cos(2θ), sin(2(θ)). What does the resulting graph look like? Twice as fast...horizontal dilation by 1/2
Upgraded an old @HungryToTeach lesson to a @desmosclassroom activity for a recent PD on FEEDBACK.
Different types of feedback in here..including some fun with an @openmiddle warm-up screen.
