This is a lesson slide. Not a picture of one.
Drag the point along the curve and watch the tangent follow. Every lesson is built out of pieces like this.
What makes it different
Diagrams that answer back
Drag a point, move a slider, sketch a curve. The maths updates while you watch, so the idea lands before the formula does.
It notices when you are stuck
Get one wrong and the lesson detours into a smaller explanation built for that exact mistake, then puts you back where you were.
A tutor that can see your screen
Ask a question and the tutor already knows which slide you are on, what you answered and where you went wrong.
What you can learn
Free while it is in beta.
No card, no trial timer. We will say so clearly and well in advance if that ever changes.
