Forge equations into living curves

A pro-grade graphing engine. Plot any function, trace points, layer curves, and explore calculus visually with butter-smooth pan & zoom.

The trigonometry command center

Identities, equations, the unit circle, special triangles — every trig concept in one neon-drenched workspace.

See sine, cosine and tangent breathe

Watch sin, cos, tan, sec, csc, cot transform in real time as you tune amplitude, period, phase and shift.

Theorems made visible

Drag points, rotate chords, watch tangents kiss the curve. Every circle theorem, animated and interactive.
