Answer to Question #231356 in Chemical Engineering for pavani

Question

16)Find Laurent series expansion of the function 2z/ z²-3z+2 in the regions

2<|z+1 <3 and |z-1|> 3.

Answer 1

The function is given as:  2z/ z²-3z+2

The regions: 2<|z+1 <3 and |z-1|> 3

We can expand the Laurent function as follows:

The first expansion we generate is:

Then we can proceed and conduct more integration and expansion to generate a function that lies between 2<|z+1 <3 and |z-1|> 3

In this case, we have a function that lies between the provided regions:
