Homework Statement
Determine the location and nature of singularities in the finite z plane of the follow function and apply Cauchy Integral Formula
Homework Equations
g(z) =
sin 2z
-------
z^15
The Attempt at a Solution
I know there is a pole of order 14 at z = o
but I'm a bit confuse when i apply the Cauchy Integral Formula
{sin 2z } / z
------------
```z^15
= 2 pi j { d ^13 f(z) / dz}
```````-----------------
`````````````13!
= 2 pi j / 13! <-- correct ?
many thanks! :)
