Could someone please show me how this problem is done, maybe even with a graph somehow? Thanks

**bobpursley**, Friday, August 28, 2009 at 5:09pmVectors are directed. When the problem says " is directed along the negative x axis" IT DOES NOT MEAN that. It means the vector is in the same direction as the negative x axis.

Draw from the origin the A vector. At its tip,put a little arrow head. Now, in the DIRECTION of the negative x axis, from the tip of A, draw B.

A+B will then be the vector from the origin to the tip of B.

Now for A-B. From the tip of A, draw B but in the direction of +x axis. From the origin to the tip of that reversed B is A-B.
