This course focuses on the complex function theory and Fourier series widely applicable to the field of science and engineering.
This course has two aims. The first is to understand the derivative and integral of the complex functions. The other is to understand the basic of the Fourier analysis.
By the end of this course, students will be able to:
1) explain the basic concept of the complex function theory.
2) understand the derivative and integral of the complex functions and calculate the integral of the real function by means of the residue theorem.
3) explain the conformal map for the holomorphic function and solve two-dimensional Laplace equations.
4) explain the concept of the analytic continuation.
5) explain the concept of the Fourier series for the periodic functions and obtain the series coefficients.
