In Region 2,

1

. Write the convergent series in Region 2, for

f(z)=(1)/((z-1)(z-2))

around

z_(0)=1

, as a sum over the integer

n

. Note that the lower limit on

n

in the second sum has changed! You'll thus have to enter the coefficient for the

(z-1)^(-1)

\ term separately. (If you want a hint, think about why that is).
