3.4.2 Vector Addition

Given two vectors, and , you can add them together to define a diagonal vector, which in turn specifies a parallelogram as shown here:

Illustration

The two vectors form two of the sides of the parallelogram and the diagonal specified by the addition of the two vectors defines the upper-right corner, which in turn specifies the other two sides of the parallelogram.

The following shows how vector addition is done:
