Vector Addition

Scroll to the bottom of the page to view the applet.

The blue vector is the resultant of the red and green vectors (addends). You can:

At the top of the applet, both the rectangular and polar coordinates of the two addends and of the resultant are displayed in real time.

Note that the vector directions are measured from the positive x-direction (East), and are counted positive in the counter clockwise direction and negative in the clockwise direction, as shown in the figure below.
