Hi,
when I do:
sage: z(x)=(e^(x^2))*e^(-(x^2));z
I get:
x |--> e^(-2*x^2)
also :
sage: (e^(x^3))*e^(-(x^3))
e^(-2*x^3)
strangely enough:
sage: e^x*e^(-x)

I have been looking at this for some time now and I don't think this
is a maxima problem (don't believe me I barely know what I'm doing)
I opened ticket #5837 and attached the patch.
I also noted there is a more general ticket #5418, can I attach an
enhancement to the signature function here? I think it may be useful
for other people too.
exitos,
Luis Berlioz

Quadratic form in 3 variables over Rational Field with coefficients:
[ -3 4 0 ]

If I try to get the diagonal form:
