Multivariable Calculus Lab
Part of Princeton Labs, with PHY 103 Lab. The More labs link in the sidebar goes to the Princeton Labs page.
An interactive multivariable calculus study site. The lessons follow the order of Princeton MAT 201 (Fall 2026). 33 lessons in 4 units, plus an optional review of the prerequisites (derivatives, integration, area between curves, conic sections, parametric curves, polar coordinates, series) and a Key formulas page; each one states the key idea, shows it in a 3D view and/or 2D map you can drag around, and ends with check-yourself questions.
