Math tools

Graph Visualizer

Plot and explore functions on an interactive Cartesian grid — zoom, pan, trace, and compare multiple functions at once.

Function Explorer

Transform, compose, and invert a function with animated parameter sliders, then read off its intercepts, extrema, and asymptotes.

Derivative Explorer

Drag a point along a curve to see its tangent line, instantaneous slope, and linked derivative graph — up to the third derivative.

Integral Visualizer

Shade the area under a curve, compare Riemann/trapezoidal/Simpson approximations, and watch the accumulation function grow.

Equation Editor

Write math in plain text or LaTeX and see it typeset live — variables, fractions, roots, sums, integrals, derivatives, matrices, and more.

Matrix Calculator

Add, multiply, invert, row-reduce, and find eigenvalues of matrices — with step-by-step row operations and a system-of-equations solver.

Complex Plane

Plot complex numbers in rectangular or polar form, drag them on the plane, and see addition, multiplication, powers, and roots as rotation and scaling.

Prime Generator

Watch the Sieve of Eratosthenes eliminate composites step by step, then test, factor, and explore numbers of any size.

Geometry Canvas

Construct points, lines, circles, and polygons with compass-and-straightedge tools — drag a point and everything built on it updates live.

Probability Simulator

Run dice, coins, cards, spinners, and custom distributions through Monte Carlo simulation and watch the results converge on the theoretical probability.

Fractal Explorer

Zoom into the Mandelbrot and Julia sets with smooth continuous coloring, or watch the Koch snowflake, Sierpinski triangle, and a fractal tree build recursively.
