Enter the x,y, and x coordinates of two different vectors into the calculator. The calculator will display the inner product of those two vectors.

## 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

How to calculate an inner product

**First, determine the vectors a and b.**Find the x,y, and z coordinates of the vectors.

**Next, calculate the magnitude and angle.**Calculate the magnitudes of vector a and b and the angle between the two vectors.

**Calculate the inner product**Calculate the inner product using the equation above and the information from steps 1 and 2.
