- A function f is analytic at a point z0 if f can be expanded in a convergent power series centered at z0. _____
- A power series represents a continuous function at every point within and on its circle of convergence. _____
- For f(z) = 1/(z − 3), the Laurent series valid for |z| > 3 is z−1 + 3z−2 + 9z−3 + … . Since there are an infinite number of negative powers of z = z − 0, z = 0 is an essential singularity. _____
- The only possible singularities of a rational function are poles. _____
- The function f(z) = e1/(z−1) has an essential singularity at z = 1. _____
- The function ...
