Both are excellent for exploring a function. Trac is for the next step: building a lesson as slides, where each click reveals the next piece and the graph, pendulum or circuit moves with it.
The full editor: every animation, all text, maths, graphs, shapes and science objects. 3 decks online, unlimited in your browser, share links, and MP4 export with a small badge.
I make maths slides where the idea moves instead of sitting there. This one is a wheel rolling along a line to draw a cycloid, then three balls dropped from different heights on the same curve reaching the bottom together (the tautochrone). The slide is built in Trac , which I made. The full editor is free and runs in the browser.
I would like feedback from people who teach: which topic would you animate first, and what stops you from using moving slides in class today?
Tracé makes animated maths and physics slides in your browser. Type an equation and get a live graph, reveal ideas one click at a time, write your own animations in a few lines, solve a science problem, or describe a lesson and let AI build it.
