Calculate the dot product (scalar product) of two vectors in 2D or 3D space. Also computes the angle between vectors.

A · B = 11.00
|A| = 2.24, |B| = 5.00
Angle: 10.30°
cos(θ) = 0.984

Formula: A·B = A₁B₁ + A₂B₂ + A₃B₃. Also A·B = |A||B|cos(θ).

Dot Product (Scalar Product)

The dot product of two vectors is a scalar value equal to A·B = |A||B|cos(θ). It measures how much one vector extends in the direction of the other .
