I understand the Mathematica has the capability to solve certain problems analytically. Laurent Series and Residue Calculus Nikhil Srivastava March 19, 2015 If fis analytic at z 0, then it may be written as a power series: f(z) = a 0 + a 1(z z 0) + a 2(z z 0)2 + ::: which converges in an open disk around z 0. A consequence of this is that a Laurent series may be used in cases where a Taylor expansion is not possible. Taylor Series Calculator with Steps Taylor Series, Laurent Series, Maclaurin Series.

Can anyone direct me to someplace where I can get a feeling for what this aspect of the software is capable of? In mathematics, a series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other, to a given starting quantity. Series[f, {x, x0, n}] generates a power series expansion for f about the point x = x0 to order (x - x0) n, where n is an explicit integer. Find the Laurent Expansion of in the region . It will then automatically combine series, truncating to the correct order. The Laurent series is a representation of a complex function f(z) as a series. 5. ComplexExpand[(x+I y)^2] x 2+2 " x y#y ComplexExpand[1&(x+I y)] x x 2+y #" y x2 +y For example, we take zn= n+ 1 2n.
