Differential Equations for Engineers
equations have an analytical solution, so it is useful to understand a basic numerical method. Then the analytical solution methods for separable and linear equations are explained. We follow the dis-cussion of each theory with some simple examples. Finally, …

5. Taylor and Laurent series Complex sequences and series
www.math.hkust.edu.hk5. Taylor and Laurent series Complex sequences and series An infinite sequence of complex numbers, denoted by {zn}, can be considered as a function defined on a set of positive integers into the unextended complex plane. For example, we take zn= n+ 1 2n so that the complex sequence is {zn} = ˆ1 + i 2, 2 + i 22, 3 + i 23 ...
