WebTo use this add-on function, we need to first load the Graphics`PlotField` package. (Note the use of backquotes.) Once the package is loaded, we can use the PlotVectorField function to plot our vector fields. Like what we have seen in ParametricPlot3D, we need to tell Mathematica to evaluate the Gradient before plotting the vector field. Webgraphics package called PlotField which is needed to construct the direction fields. This is accomplished by the command below. In[1]:= Needs@"Graphics`PlotField`"D We are now going to define a function called dirfield which will construct a direction field plot. The function will ... = Ü Graphics Ü Even without plotting any specific ...
