2、Learning Goals and Objectives

By teaching to let students
1. Correctly understand and grasp the basic concepts and methods of complex function. Master several complex representation methods, and to carry out each conversion; understand the differences and similarities of the Complex Functions and Real Variable, deepen the understanding of the complex function by comparison.

2. Understand the derivative of complex function and the basic concepts of ****ytic function, master the method that complex function can lead judge and ****ytical

3. Understand the concept of complex function integration; master fundamental theorem of Cauchy -Gu Saji and its extension - Composite closed theorem, familiar with the Cauchy integral formula, and can apply the Theorem in the proper use.
4. Understand the basic concept and nature of series of complex and the complex function, focusing on how to change the ****ytic function expansion into power series and Laurent series.
5. Understand the concept of residue; master the basic methods in which how to calculated integral of the closure of surface according to the residue theorem.
6. Understand the concept of conformal mapping.
7. Gradually develop and establish the ability of solving basic problems by complex function.
8. Master the concepts of Fourier transform and Laplace transform and methods of its common use in engineering practice.
