Is there a way for me to see the slope field for a differential equation such as dy/dx=2x or similar first-order seperable differential equations? > > S Jonak Steven, You can use PlotVectorField (with normalized arrow length) to plot slope fields. This is an example with y'=2x : <<Graphics` PlotVectorField[{1,2x}/Sqrt[1+(2x)^2],{x,-1,1},{y,-1,1},Axes->True] --- jcp
