Teaching

I am not teaching this semester, but I am supervising two groups of undergraduate researchers through the Manitoba eXperimental Mathematics Laboratory, which I also organize.

Geogebra

I like using GeoGebra's 3d calculator to make interactive images for my classes. Here are some of my favorites:

• a way to visualize a directional derivative on a surface

• looking at mixed partial derivatives

• finding the max/min on a surface within a closed region

• Lagrange multipliers (use the slider to move the black curve!)

• orthogonal projection gives the "closest point"

Sage

For an undergraduate research project, I adapted some tutorials for the (free) Sage mathematical software. They're for a very specific purpose and don't cover everything, but maybe you'll find them helpful for learning! These were written in CoCalc with Sage 9.4. You can either download them to run with an installation of Sage on your own machine or upload them to CoCalc and run them there. Another good resource to run short snippets of sage is SageCell.
