Here, my first question an expression may have different type of series expansion? And second, how to find a Laurent series for $ f(z) $. Mathematica computer guide : a self-contained introduction for Erwin Kreyszig, Advanced engineering mathematics, eighth edition / Erwin Kreyszig, E. A part of the book, Complex Analysis for Mathematics & Engineering, 4th Ed, 2001, by John H. We can use Mathematica to investigate how well the complex Laurent series is "converging" in the complex plane. The topics of: complex integrals, contour integrals, Taylor series and Laurent series are all explored with computer calculations and graphs. (24:30) Find the Laurent series centered at z = 0 in the annulus between the circles of radius 3 and 4. For both series, the ratio of the nth to the (n-1)th term tends to zero for all x. 5): application of Laurent series in complex integration; Cauchy's Residue theorem; Lecture 26 (Jun.
