Being new to Maple I can't figure out how to do a 3d plot of a function w/ 3 variables. I want to be able to also do a space curve to show the constraints. Anyway, here's the function. f := proc (x1, x2) options operator, arrow; (339+(-1)*0.1e-1*x1+(-1)*0.3e-2*x2)*x1+(399+(-1)*0.4e-2*x1+(-1)*0.1e-1*x2)*x2-400000-195*x1-225*x2 end proc I am not able to show it. Thanks, Bill
