I made this shape called a quadrifolium. I found it on the website which was given to us to look at curves. I knew what I wanted to do right when I saw it. It took me a while to get the hang of the different variables within the equation, but I ended up liking the project. The image is inspired by a four leaf clover for good luck. I could use some of that for the rest of this semester. Actually, for the rest of my life.
