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.
