Laurent series for complex-valued function

Reference no: EM13130549

Consider f(z) = [(z-i)(z+4)(z-3)]^(-1) restricted to the domain of definition 0 < |z|< infinity

How many different Laurent series centered at z_0 = 0 does it have? Explain.

Discuss the convergence and divergence sets of each of those Laurent series.

Find two non-zero terms of the Laurent series which represents this f for all z outside some circle |z| = R but diverges inside the circle and find the numerical value of R. Is this function f(z) analytic at 0? at infinity? Explain.
