Hi.
Is there any way to obtain the decomposition in simple elements (don't
know exactly how to say this in english) of a fraction of the form :
1
-------------------
(1-X)(1-X^2)(1-X^5)
(to obtain its formal series equivalent \sum a_nX^n, a_n being the
number of ways to pay n? using 1, 2 and 5? corners (no, there
is no such thing as a 5? corner, but there's a 5? banknote !)).
I'd like to obtain the C-decomposition, what do I have to do ?
\bye
