Manifold — a free online graphing and calculus visualiserManifold is a free, browser-based graphing tool built by Limitless for high-school and university students. Type an expression and it plots in 2D or 3D; ask for a worked solution and it shows the reasoning step by step rather than only the answer. Nothing to install and no account needed.What you can work through in Manifold

Plot 2D and 3D functions, with constants turned into draggable sliders.

Multivariable calculus: directional derivatives, tangent planes, Lagrange multipliers, double integrals and Riemann sums.

Vector calculus: both sides of Green's theorem (circulation and flux forms) and Stokes' theorem, worked out.

Linear algebra: row reduction and matrix multiplication, step by step.

Differential equations: characteristic equations, and phase portraits with each equilibrium classified by its Jacobian.

Curve fitting and probability distributions, including cumulative distributions.
