FilledSmallSquare Residue[expr, x, ] finds the residue of expr at the point .

FilledSmallSquare The residue is defined as the coefficient of (x - )^-1 in the Laurent expansion of expr.

FilledSmallSquare Mathematica can usually find residues at a point only when it can evaluate power series at that point.

FilledSmallSquare See Section 3.6.10.
