Step 5 just gives the shorthand notation for a vector from a point A to B in a figure. Outside of a figure, I will use the notation AB to denote the same vector because it not easy to put an arrow over the two letters AB . The first first kind, head to tail addition of vectors representing movements, was described in the previous lessons. In mathematics, you should remember saying how to do a calculation or operation defines it. Remember this principle.
Vector addition represents as given here represents a geometric calculation.
So the order of addition is not important. That is, vector addition commutes. Remember this when we talk about real and complex numbers below. The applet illustrates the parallelogram law for the addition of vectors with tails at the origin. All trademarks and copyrights on this page are owned by their respective owners.
