`d = V * U`

Enter a value for all fields

The **Vector Dot Product** (**V•U**) calculator * Vectors U and V in three dimensions* computes the dot product of two vectors (V and U) in Euclidean three dimensional space.

**INSTRUCTIONS:** Enter the following:

- (
**V**): Enter the x, y and z components of vector V separated by commas (e.g. 4,5,9) - (
**U**): Enter the x, y and z components of vector U separated by commas (e.g. 4,5,9)

**Dot Product (d): **The calculator returns the dot product of U and V. The dot product is also called the inner product or the scalar product.

This formula lets the user enter two three-dimensional vectors (**V** and **U**) with X, Y and Z components. Note the dot product of two **unit vectors** is equal to the cosine of the angle between the two vectors.
