DOT PRODUCT CALCULATOR


Dot product calculator calculates dot product (scalar product), magnitudes and angle between two vectors. The calculator can be used for dot product calculation of 2D or 3D vectors.

Dot product calculation can be done for two different vector forms: vector components or magnitudes and angle between vectors.

The dot product formulas used for the calculations are given below.

Dot product of vectors $$\vec { A } \cdot \vec { B }={ A}_{ x }{ B }_{ x}+{ A}_{ y }{ B }_{y}+{ A}_{ z }{ B }_{z}$$
Dot product by magnitudes and cosine angle $$\vec { A } \cdot \vec { B } =\left| A \right| \left| B \right| \cos { \theta }$$
