To calculate the angle between vectors online calculator


Online calculator which helps you calculate the angle between vectors.
The angle between the two vectors is the smallest angle between vectors, one of which must be rotated to obtain the co-directional with others.
In electrical, mathematical, and engineering calculations of the angle between the vectors is expressed by (cos α) is equal to the ratio multiplied scalar values (a and b) the product of the moduli of the vectors |a| and |b|.

Specify the coordinates of the vectors in two-dimensional space:
a = (, )
b = (, )
