When I enter
f = e^-(x^2 + y^2) (x^2 + 2y^2)
It gives me a syntax::noinfo error but the output looks like the
correct textbook style function.
Also, when I try to plot it
Plot3D[e^-(x^2 + y^2) (x^2 + 2y^2), {x, -3, 3}, {y, -3, 3}]
It of course gives me not machines-size real number errors, which I am
assuming have more to do with my original syntax error.  I've tried
several variations but can't figure out what needs to be corrected.
