At point (1,1), magnitude = √ 2 and direction 45 degree with horizontal.
At point (-1,1), magnitude = √ 2 and direction 135 degree with horizontal.
At point (-1,-1), magnitude = √ 2 and direction 225 degree with horizontal.
At point (1,-1), magnitude = √ 2 and direction 315 degree with horizontal.
At point (2,2), magnitude = √ 8 and direction 45 degree with horizontal.
At point (-2,2), magnitude = √ 8 and direction 135 degree with horizontal.
At point (-2,-2), magnitude = √ 8 and direction 225 degree with horizontal.
At point (2,-2), magnitude = √ 8 and direction 315 degree with horizontal.
:O
This is the face I pull when I read these equation-type articles :P
