Sorry that does not help. I need a way to cast from a SymbolicEquation type to a MaximaElement type. Please see my post :) On Dec 23, 3:55 pm, "John Cremona" wrote: > 2008/12/23 bsdz : > > > > > Hi, > > > Is it possible to convert a SymbolicEquation into a MaximaElement > > easily? The opposite

[sage-support] Convert a SymbolicEquation into a MaximaElement

2008-12-23 Thread bsdz
Hi, Is it possible to convert a SymbolicEquation into a MaximaElement easily? The opposite to: - maxima('x^2 + y^2 = 0').sage() Something like this: - x, y = var('x y') b = x^2 + y^2 == 0 b.maxima() I would like to do some manipulations on an equation by breaking it down into terms and parts.

Hi I am new to sage and hence, not very familiar. However, while going through the documentation, I saw some examples of usage of functions that are provided by other packages like maxima, octave etc. I am bit confused, about whether I have to know all those packages before being able to use sa

Hi, as a followup on the "Arbitrary precision in cython" thread, I'd like to mention that one can directly use mpfr's implementation from within Sage: sage: RealField(150)(10).eint() 2492.2289762418777591384401439985248489896471 It only works for real numbers, but has the advantage to gu
