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.
