Taylor series expansion about x=0 (MacLaurin series)

[Conrado Badenas <Conrado.Badenas@uv.es>]

Does anyone know of a Debian package with which I could make Taylor
series expansion of simple functions?

I've tested Derive 3.0 (february 1995) for MSDOS, but it finishes the
whole memory when trying to obtain the first four terms about x=0 of

sqrt(x^6/36+(1+x/2-x/(1-exp(-x)))^2)*(12/x^2)

I have obtained manually that it should be 1+119*x^2/60-991*x^4/504, but
I would like it to be confirmed by a computer program.

Thanks!
