Boy's surface immersion of the projective plane with three-fold symmetry

Composite Fourier wave with two component harmonics

$Mandelbrot set fractal in the complex plane$

Boy's Surface

An immersion of the projective plane — a one-sided surface with three-fold symmetry and a single triple point.

Fourier Harmonics

A composite wave with its individual harmonic components shown separately.

Saddle Surface

A hyperbolic paraboloid — curves up in one direction and down in the other.

Mandelbrot Set

The classic fractal defined by iterating complex quadratic polynomials.

Polar rose curves with three, four, and eight petals

Polar Roses

Overlapping rose curves trace petals from a single trigonometric formula.

Saddle Surface

A hyperbolic paraboloid — curves up in one direction and down in the other.

Explore. Explain. Share.

Math that looks right

A full LaTeX typesetting engine and your choice of professional math fonts — every equation comes out publication-ready.

It knows what you mean

Type y = sin x or a full parametric surface — Graph Paper picks the plot type, frames the viewport, and chooses the colors. You do the math; it does the chart.
