f(z) = The function f(z) is not defined at z=0.But by L’Hospital’s rule, Since the limit exists and is finite, the singularity at z=0 is a removable singularity. 9. Evaluate where C is Given both lies outside c. Therefore 10. Find the residue of the function f(z)= at a simple pole. , z = 2 is a simple pole.

F /(x) = x n means F(x) = , n ( –1 so if F /(x) = x 5 + 7x 3 – 3x + 6 then F(x) = but if the differentiation involves the chain rule as well we must anticipate the term generated by the chain rule as it will not be in the original function.
