I'm new to Maple and just starting a ODE class. I attempted to do a Directional Field plot using DEplot. The plot displayed only Q3 and no mater what I tried would not plot the other quadrants. My inputs: with(DEtools): desgn := diff(y(x),x)=-x/y DEplot(desgn,y(x),x=-10…10,y=-10…10); Seems simple enough is there something I’m missing? I tried to change the range by the right click over the plot; did nothing. Sorry if this is overly simple but, I’m still learning… Thanks for any help anyone can offer.
