Parametric curve - Silly Goose

Examples of parametric curves, created by single pairs of non-piecewise parametric equations. I came up with the method for creating such curves. My method utilizes and reinforces high school level Math skills (domain/range, function transformations, function addition, function composition, writing sinusoid equations, parametric equations). Inspired by the "Batman Equation" of 2011 and Wolfram Alpha's "person curves." Instructional how-to video playlist here.

Inspired by the custom "silly goose" rubber stamp that I illustrated/ordered. Used when grading papers and encountering a forehead-slapping mistake (e.g. 2+3=6).
