3.1 Consider the following complex function: f(2)= (z + a)(z + b), where a > b>0 are real. Now: (a) State why f(z) is not single-valued, [2] (b) find the branch points and isolated singularities of f(2), and state the nature of the isolated singularities, [4] (c) evaluate the residues of f(z) at its isolated singularities, assuming 0 < arg z < 2π, [6] (d) compute the integral fƒ(z)dz, where y is the contour in Fig. 1, and [4] (e) use the previous results to show that 2π ya - Vb dz √3 a-b [9] So (2x + a)(2x + b)² Z=
