RE: SImple Plot3D issue


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}];

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.
