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.

• Open index.html in any browser. No install, no build step, no internet needed (except Google Fonts).
• Sections: Review (optional) · 1 Vectors & space · 2 Several variables · 3 Multiple integrals · 4 Vector calculus · Formula sheet.
• Navigation: course outline on the left ("All lessons" menu on phones) with topic search; Prev/Next buttons or the ← → keys. "Reset" restores a lesson's default settings.
• Link straight to a lesson with #stokes, #polar, etc.
• Hosted with GitHub Pages (Settings → Pages → Deploy from branch main, folder /).
