I have some past exam questions that I am confused with
I'm not sure how to approach this, I'm completely lost and just attempted to solve a few:
a) it says has a pole of order 5, so
so then I guess the condition is ? But that's just applying the formula for the coefficients...
c)
so the coefficients are ?
d)
so,
g)
h) or
for e) and f), I'm not sure what the relevance of the essential singularity is
Well, I think you can see I'm clearly lost, would appreciate if you could help me out.
