. Use the Taylor expansion of the function f(z) = 1 1+z [8] 4
centred at the origin z = 0, together with the extended Cauchy
Integral Formula to evaluate the contour integrals I C dz/ z^ k (z^
4 + 1), k = 0, 1, . . . , where C is any positively oriented simple
contour going around the origin that is interior to the circle of
radius 1 centred at z = 0.
