# Math Help - Laurent series

1. ## Laurent series

Hey guys.
I need to develop this function into Laurent series.
I used the Sin Taylor series and got what I got.
Now, is there a trick or something to get the z-2 inside series or is this enough?

Thanks.

If you're expanding around z = 2 then you need to get the Taylor series of sin z around z = 2. Then multiply it by 1/(z - 2) to get the required Laurent series.
