All Mathematica symbols begin with capital letters. So I think you mean to use 'E' rather than 'e'. Plot3D[E^-(x^2 + y^2) (x^2 + 2 y^2), {x, -3, 3}, {y, -3, 3}]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: jtolman at gmail.com [mailto:jtolman at gmail.com] To: mathgroup at smc.vnet.net I am trying to plot the 3D function e^-(x^2 + y^2) (x^2 + 2y^2) Plot3D[e^-(x^2 + y^2) (x^2 + 2 y^2), {x, -3, 3}, {y, -3, 3}] I get not machine-size real number errors. When I try f = e^-(x^2 + y^2) (x^2 + 2 y^2) I get a Syntax::noinfo: insufficient information error, although the output looks like a valid textbook style equation. I've tried several variations on input but can't figure out where the syntax mistake is.
