Now press the Toolbox key (the "B" key) and then type in plotfield so that the cursor highlights the command "plotfield." With plotfield highlighted, press the [Help] key and then select "Example" from the menu. Press [Enter] twice, then press [Plot].

Basically, you created a geometry element named GA whose definition is:

plotfield(x*sin(y),[x = ((-6) .. 6),y = ((-6) .. 6)],'normalize')

For more information, see the built-in Help for plotfield.

Thanks! I can combine this with plotode and have it work to perfection. Very cool. Thanks so much!

Teaching Calculus III and ODEs will be a whole different experience now!
