Hi, I assume you want to plot the solution to the ODE. E.g numerically: y/.NDSolve[{4x^2+y[x] y'[x]==0,y[0]==1},y,{x,0,0.5}][[1]] Plot[sol[x],{x,0,0.5}] or smybolically: sol=y/.DSolve[{4x^2+y[x] y'[x]==0,y[0]==1},y,x][[1]] Plot[sol[x],{x,0,0.5}] hope this helps, Daniel noxon wrote: > if anybody can give me some examples of ploting some integral curves, i > would be very gracious... for example: 4x^2+2yy'=0 ....how can i plot > that, i've tried everything but there is no curve.... > > > -- Daniel Huber Metrohm Ltd.
