A + B = B + A
Two vectors are equal if they have the same magnitude and the same direction.
Vector Addition (Geometric)
The figure above illustrates how vectors are added to each other geometrically.
Place the tail (the initial point) of one vector at the tip of the other vector, then
connect the exposed tail to the exposed tip. The vector formed is the sum of the first
two. This is called the “tip-to-tail” method of vector addition.
- Add the following two vectors.
