In problem 79 finding zeros of (1-e^z) sinz alone is not enough to say that they are simple pole. Showing derivative of (1-e^z) sinz doesn't get vanishes on those zeros will say that those zeros are simple poles of the function

Mam in 82 question in first option u did in wrong way i think bcz if g holomorphic take z-1 and when u will do g/z then it has sing at z =0 so g/z is not analytic


First option is correct for correct approch of this option is that h(z) = g'(0) and g is entire and nth derivative is also entire so h is entire so first correct

If i am wrong please correct me
