Math 21a Models
(In progress)
Thermoformed using 0.04" PETG on the Formech 686
Description:
I was hired by the Harvard Math Department to fabricate new thermoformed surface
models for Math 21a. These models are created by vacuum-forming plastic over a
3D-printed buck of the function
\[
f(x,y) = \frac{1}{30}\left(-2x^{3} + 18x^{2} + 3xy - 3y^{2} - 51x + 9y + 107\right)
\]
which is used in the course to help students visualize multivariable calculus concepts. The clear, durable surfaces allow students to draw on them and physically explore level sets, contours, and partial derivatives in an active-learning setting.
