Homework Help: physics

Posted by benjamin on Friday, August 28, 2009 at 3:14pm.

Vector A has a magnitude of 8.00 units and makes an angle of 45.0 with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods, find (a) the vector sum A + B and (b) the vector difference A B.

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