| 2012-03-12 09:24:47 +0100 | asked a question | how to use certain maxima functions (e.g. ratsubst)? I cannot figure out how to use maxima functions like ratsubst within sage. For example: X = maxima('x^2') Now I'd like to substitute x with k. In Maxima, this is done via: X: x^2; ratsubst(k, x, X); How do I call ratsubst from Sage? If I use X.ratsubst('k', 'x') then it simply prints out 'x'... |

| 2012-03-12 05:55:24 +0100 | asked a question | divide numerator and denominator by certain value Hi, is it somehow possible to divide the numerator and denominator of a fraction by the same value? For example, (ab + c)/(bd + a + c) gets (a + c/b)/(d + a/b + c/b) if I divide it by b. |
