Function of complex variable is not only an important specialized course in university mathematics and applied mathematics but also a basic major course in terms of electric, automatic and communication departments. Besides, the results of various subject areas are formed with function of complex variable as the basis. Especially in recent years, with the rapid development of communication technology, the theory as well as approaches of function of complex variable are expanded and perfected and various talents are able to apply its theory as well as approaches into engineering practice, which ask new requirement for the teaching course. This paper studies on the integration of mathematical modelinginto function of complex variable into so as to further strengthen the practical function based on updating teaching contents, introducing modeling cases, reforming teaching approaches etc.
