CraftMath Graphs

Graph, inspect, and rotate.

Plot multiple functions or relations, find common points of interest, and build a 3D solid of revolution from your curve.

Expressions

Use forms like y=x^2-4, x=y^2, x^2+y^2=9, or y=sin(x).

x-min x-max y-min y-max

Zeros, extrema, and intersections are estimated numerically.

Solids of Revolution

Enter a function, choose an interval, and rotate it around an axis. Drag the 3D view to inspect the surface.

Function y=\sqrt{9-x^2}

from x to x

Rotate about Region boundary Rotation sweep 0 degrees

Start with the filled region, then sweep it with the slider.
