## Inner Product Formula

The following equation is used to calculate the inner product of two vectors.

a * b = Ma * Mb * cos (x)

- Where a and b are vectors
- Ma and Mb are the magnitudes of those two vectors
- x is the angle between vectors a and b

To calculate the inner product multiply the magnitudes of vectors a and b by the cosine of the angle between them.

## Inner Product Definition

An inner product is a mathematical scalar value of the multiplication of two or more vectors of an undetermined size.
