About the Vector Calculator

Every common vector operation, in 2D or 3D, with steps and a plot.

What it is

The Vector Calculator performs addition, subtraction, dot product, cross product (3D), magnitude, unit vector, and angle-between calculations on two input vectors, in either 2D or 3D. A 2D visualization plots both vectors and their sum as arrows from the origin.

Features

2D and 3D modes

Toggle dimensions; cross product available only in 3D.

Full operation set

Sum, difference, dot and cross product, magnitude, and unit vectors.

Angle between vectors

Computed via the dot-product formula, with the zero-vector case handled explicitly.

2D visualization

Vectors and their sum plotted as arrows from the origin.
