Plotting Direction Fields with Mathamatica7

  1. Jun 1, 2010 #1
    Can someone please explain to me how one plots direction fields of differential equations in mathamatica 7? Two examples are
    y'= -1-2y

    Thank you

    Use StreamPlot[{x'[t],y'[t]},{x,-a,a},{y,-b,b}]

    and in the case of just y'=f(x,y), use:
