Great. Ask on the sympy list if you have any problems. He's also got
a branch https://github.com/sympy/sympy/pull/543 that should improve
the integration capabilities of SymPy even more (esp. for definite
integrals). It should be merged pretty soon.

Hello everyone!
I tried using the HasseDiagram and rank features of Sage as described on
http://www.sagemath.org/doc/reference/sage/combinat/posets/hasse_diagram.html
Things worked ok, but when I then tried:
m= Matrix([[0,1,1],[0,0,1],[0,0,0]])
g = DiGraph(m)
h2 = HasseDiagram(g)
h2.rank(2)
I go
Hi
I looked around quite a bit but probably not in the right places?
I found I can define a vector function and how to get its derivative
vector function.
Is there a way to get at the component functions and/or a way to
calculate the magnitude function of rprime?
var ('t')
r=vector(t,t^2,t^3)
rpri
Hello!
I discovered today that if I list_plot two lists on the same graph,
the order of the curves depends on the value of the 'plotjoined'
parameter.
I want to plot one list with joined points (theoretical curve) and
the second list with scattered points (experimental points). Naturally,

But setting
the 'plotjoined' parameter to "False" puts them to the back, the
theoretical curve overlaps them, and some of them are not visible.
In any case, could somebody please tell me how to get the desired
result in Sage?
I seem to succeed by setti

Hi,
I'm trying to solve a differential equation with unit step, e.g. the

The result is 0 for 05 (it's a simple integ
Note that: sum(a,[]) gets incredibly slow when a contains a lot of lists (it's
runtime complexity is kwadratic in the number of lists in a). So it's better to
do:
l=[]
for i in A:
l.extend(i)

Or maybe I'm just bad at looking. DiGraph() is actually fairly
