I have now a little bit improved the package of my polynomial and rational fractions utilities over GiNaC (0.6.4) It provides now gcd normalization, factor (square-free and rational roots), partfrac & integrate (assuming factor works on the denominator), for example: integrate '1/(x^4-1)^5' returns -1155/8192*log(1+x)-1155/4096*atan(x)+1155/8192*log(-1+x)+1/2048*(-893*x-1375*x^9+1755*x^5+385*x^13)*(-1+x^4)^(-4) # Time for (integrate)0.04 You can retrieve and test it at ftp://fourier.ujf-grenoble.fr/pub/hp48/giac.tgz Bye, Bernard Parisse
