A STARTING POINT, MADE FOR YOU

The geometry & linear algebra
toolbox.

Explore coordinates, vector products, matrices and geometric constructions.

INSIDE THE TOOLBOX

9 useful places to start.

Starter collection

Each tool states its coordinate convention and numerical limits. Matrix results use floating-point approximations.

Calculate lengths, dot and cross products, angle and vector projection.

Add, multiply, transpose, invert or find a determinant for matrices up to 6 × 6.

Solve a plane triangle from two sides and their included angle, or one side and two angles.

Find the circumcentre, radius and equation of the circle through three plane points.

Translate 3D Cartesian coordinates and radius/azimuth/polar-angle coordinates.

Convert angle units with clearly labelled standards.

Find the area, ring width and boundary lengths of a circular ring.

Calculate the volume, base radius and surface areas of a sphere cut by a plane.

Find the volume and surface areas of a truncated right circular cone.

SMALL TASKS. LESS FRICTION.
