In arithmetic, a Laurent sequence is an growth of a operate as a sum of constructive and unfavorable powers of (z – c), the place c is a posh quantity. It’s a generalization of the Taylor sequence, which solely accommodates constructive powers of (z – c). Laurent sequence are helpful for representing capabilities which have singularities at remoted factors.
To find out the Laurent sequence of a operate, we are able to use the next steps:
