Type any function, drag the slider along the curve, and watch the tangent line change live and see the value on its derivative graph.
Type any function, drag the slider along the curve, and watch the shaded area under it accumulate live onto its integral graph.
Drag a bead along a wire to create your own motion, watch the position-vs-time graph draw itself live, then play it back.
