Converting from the S domain to the Z domain

I'm having some problems converting this equation in the laplace domain.



I understand that


Can someone please explain the step of convertion.

I'm expecting something with cosines in.

Thanks
Jez

I think it would be helpful if you provided more context, like do you have to use the map from the s to z domain you quote, also why you expect to see cosines, ..
