[sage-support] Re: multivariable limits ?

2010-09-01 Thread kcrisman
Dear Laurent, Sage uses Maxima for such computations - see http://maxima.sourceforge.net/docs/manual/en/maxima_18.html#Item_003a-limit As far as I know, Maxima does not implement such limits. It looks like Maple does and Mathematica doesn't, from a brief online check - not surprising, I think.

[sage-support] multiple commands in sage simple server

Hi, is there any way to compute multiple things via the simple server? I mean, instead of sending 3 requests https://blabla/simple/compute?session=...code=a=2 https://blabla/simple/compute?session=...code=b=3 https://blabla/simple/compute?session=...code=a*b I want something like

i dont think my previous example was clear so ill try to do a new one that achieves the same result let F=f(x,y) where degx is the degree of F wrt x and degy is the degree of F wrt y G=f(t,z) got vector (G^0,G^1,G^2,...,G^degx)

I'm not sure I completely understand your question, but maybe this response will contain all the ingredients you need. First, since you are working with polynomials, I suggest creating a polynomial ring in the variables x and y, and then your polynomial f. sage: R.x,y = QQ['x,y'] sage: f = 3*x^2

[sage-support] Problem doing symbolic computations (bug in Pynac ?)

2010-09-01 Thread Jean-Pierre Flori
Hello, I'm using Sage to do some symbolic computations. What I am basically trying to do is to compute sums made of terms of the form : cst_{i_0,...,i_d)*b_0^{i_0}*...*b_d^{i_d}*2^{-b_0-...-b_d} where the b_i are variables (i.e. a product of an exponential with b_i in the exponent by a
