I am very confused by the wording of this question, it reads:(adsbygoogle = window.adsbygoogle || []).push({});

Determine the nature of the singularities of each of the following functions and evaluate the residues (a>0)

a) 1/(z^2 + a^2)

b) 1/ (z^2+a^2)^2

Hint. fr the point at infinity use the transfor,ation w = 1/z for |z| -> 0. For the residue transform F(z)dz into g(w)dw and look at the behavior of g(w).

What does this mean, what are they asking?
