Type in the magnitude and direction of vectors A and B (degrees, numbers only), and watch as the program adds your vectors together. The green line is the sum vector. For more detailed vector information (directions, magnitudes, x and y-components of each vector), see inside the project and show all of the lists. :D ---WHAT IS THIS USED FOR?--- One use for vector addition is in physics, where vectors can be used to simulate velocity. A real life use for vector addition is in airplanes, where vectors can be used to correct for wind in a plane's flight path.
Inspired by my Physics textbook, and my annoyance at the time it took to complete some problems in it. :P
