Hi folks,
Assume that for fun one want to deal with an expression containing
non-integer powers of a certain variable x. Take as an illustration
the following expression;
******)
expr = Expand[Sum[(a*n +b*n -c)*x^(n+0.12/n),{n,1,4}]];
(**
One knows in advance that a power of x is, for example, 1.12 and
we want to know its coefficient. Apparently Coefficient and Collect
work only with integers. Is there a way to deal with this situation?
Salut,
Rojas
