Derivatives and integrals

Derivatives and integrals made visual: tangent to a graph, area under a curve, Riemann sums, symbolic differentiation and formula references.

Pick a tool. Type your own function and see it drawn – with a tangent (derivative) or shaded area (integral).

Derivative at a point

Compute the derivative of a function at a point and see the tangent line – its slope is the derivative.

Differentiate a function symbolically (2x² → 4x). Type your own function and get its derivative.

Compute a definite integral as the area under a curve between limits, with the area shaded on the graph.

See how Riemann sums approximate the area under a curve with rectangles – why the integral is an area.
