Angle between vectors presented on the picture below:

angle between vectors

It can be calculated using the formula for scalar vectors product:

definition of the scalar vectors product


definition of the cosine of the angle between vectors

If one changes vectors relations to coordinate one, formula for cosine angle between vectors is also changes:

cosine of angle between the vectors in coordinate form

, where vector a coordinates and vector b coordinates
