Challenge: 1. With the triangle function you can make things that are a kinda round but not like completely round like a circle. Some examples are like the steering wheel on a ship, or a ferris wheel, or even gears. This is because the triangle functionis round but on the edge it has these points which are there because triangles don't have round spots. 2. I have noticed that the if x degree X the # of repeats equal 360 or higher that it will go all the way around which will make it round. And I also noticed that the lower number that x is then the less open space there is in the inside of the circle and the higher number that x is then the more space there is in the inside of the circle.
