I made an ellipse, but then I got bored, so I started messing around with the equation and got a weird effect that makes it look like it's 3d rotating, so I decided to keep it. How Ellipses on scratch work: Ok so the Cos represents the Cos on a unit circle. Same with the Sin except the Sin is for the y axis. You use the Cos and Sin to draw a perfect circle because that's how the unit circle draws out. But to make an ellipse we multiply the Cos by the width to stretch it, and the Sin by the height to Stretch it. Another way to think about it so the triangle in the unit circle goes in a circle motion, so if the (cos, sin) point had a pencil, and went from 0-360, it would draw out a circle, but the width and height stretch out the location of the (cos, sin) point.
