Thanks for help.
I will try to explain why i need this. I have an expression, that contains different powers of "A". The simplest example of such expression is:
1/(A*B)+1/(AC)+1/(A^2*E)+1/(A^2*D) (But it can contain terms like 1/A^3, 1/A^4 and so on)
in my case, "B","C","E","D" is some complicated expressions.
. I know, that "A" is big, so i want to get power series expansion, like 1/A*(some_expression) + 1/A^2*(other_expression)+...
After this, i want to study "some_expression", "other expression" separately.
P.S. Sorry for my rough english
