Vector Calculator
Dot product, cross product, magnitudes, angle and projection between two 2D or 3D vectors.
How to use the Vector Calculator
- Enter or select: Vector u, Vector v.
- The results (u · v, u × v, |u|, |v|, Angle, Projection of u on v) are calculated instantly as you type.
- Use “Copy link” to share the calculation with the same input values.
Formula
- u·v = Σ uᵢvᵢ
- cos θ = u·v / (|u||v|)
