**Explanation:**
This utility illustrates the graphical and analytical methods used to add
vectors as illustrated in Sections 3.2 and 3.3 of the book. First,
each vector is represented by its components. These are related to the magnitude
of the vector and its direction by Equations 3.1. The sum is performed
by adding the components as shown in examples 3.3 and 3.4. The animation
illustrates the graphical method used in adding vectors as discussed in
Section 3.2. |
