19:34 < rickhg12hs> having some issues with partial fraction decomposition
19:37 < rickhg12hs> sage: R.<x> =
GF(2)[];((x+1)/(x^3+x+1)).partial_fraction_decomposition()
19:37 < rickhg12hs> ... generates type errors
19:39 < rickhg12hs> sage:
P.<y>=ZZ[];((y+1)/(y^2+y+1)).partial_fraction_decomposition()
19:39 < rickhg12hs> ... generates type errors also
19:41 < rickhg12hs> sage: ((y+1)/(y^2+y+1) +
(y+1)/(y^2+1)).partial_fraction_decomposition()
19:41 < rickhg12hs> ... the line above works
19:43 < rickhg12hs> sage: ((x+1)/(x^3+x+1) +
(x+1)/(x^3+x^2+1)).partial_fraction_decomposition()
19:43 < rickhg12hs> ... the line above works
19:46 < rickhg12hs> FYI:
19:46 < rickhg12hs> sage: version()
19:46 < rickhg12hs> 'Sage Version 3.4.2, Release Date: 2009-05-05'
