Course description and aims

Based on [Applied Mathematics for Engineers Ia] in the first quarter, this course focuses on basic part of complex analysis. First, we explain Cauchy's integral theorem and Cauchy's integral formula after reviewing complex line integrals. Then, we explain the Laurent expansion of meromorphic functions after classifying isolated singularities of complex functions. Finally, we explain the residue theorem and its application to the calculation of definite integrals.

Complex analysis is an absolutely essential mathematical basis of science and engineering. The aim of this lecture is to explain the basic theory and practical way to use of complex analysis by an efficient way.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
