Hi..I need to plot the slope field for a diffEQ and having problems. I have a Maple 14 program that I just had to reinstall due to a virus and hoping that isn't the problem.  I'm very new to Maple and I'm not a good programmer, so any light you can shed on my problems would be much appreciated.  When I enter the problem, I don't get any error message or anything...just a blank return!  This is what I tried:

with(DEtools):

DEplot (diff (y(x), x)=  x+1/2*(y(x))^2, y(x), x=-5..5, y=-5..5, {[-2,0]}, linecolor=blue);

 

Any help would be apprecitated!  Thanks!
