18. (3 pts) Using the geometric series formula and the series for exp, find the first four terms in the following Laurent expansion: e 22(22 +1) +) Cnan = +... n=-2 (you do not need to state a formula for all the terms.) What is the domain of convergence of this infinite series? (hint: it is not a disk, and it is contained in, but not the same as, the set of all points where the function is analytic)
