# Angle between two vectors

This online calculator finds the angle between two vectors

This calculator finds the angle between two vectors given their coordinates. The formula and the explanation can be found below the calculator.

### Finding the angle between two vectors

We will use the geometric definition of the 3D Vector Dot Product Calculator to produce the formula for finding the angle.

Geometrically the dot product is defined as

thus, we can find the angle as

To find the dot product from vector coordinates, we can use its algebraic definition.

Thus, for two vectors, and , formula can be written as

This is the formula used by the calculator.
