I think the way that I figured out which equations to use where by picturing what I needed. I would look at each facial feature and think of what equation I could use to make something that resembled it as close as possible. For example, on the hair I couldn’t exactly figure out what do put for it. So I looked at what possible equations I could use and what they would look like and I decided to use cosine. Some challenges that I ran into where that I couldn’t make some of the equations look exactly like I wanted them to look, however I still made them look as close to me as possible by changing different parts of the equations. Some strategies that I used where, like I said putting in different equations and seeing which one looks the best to keep. This assignment really helped me visualize just how vast and infinite different relations are. You can come up with infinite different shapes and lines just by using the different equations we know.
