Returning a wrong result is never intentional.

OK. I just wanted to be sure. Sometimes there is strange behavior in
SymPy that turns out to actually be intentional. This is now issue
1604.

Can someone tell me, is this a bug? If this is intentional, can
someone please explain why? If I remember my integration by parts
correctly, that second term should be Integral(D(g(x), x)*exp(x), x),

You are running into numerical issues (underflow, I belileve) because
of scaling issues. If you don't normalize your polynomial then the the
coefficients of the polynomial are

If a wire frame of such things is sufficient, Eck's xModel applet is a
simple way to generate a wireframe of a surface and then be able to
rotate it, all throug
Yep.
