### 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.

### Student learning outcomes

・Students are expected to understand Cauchy's integral theorem.
・Students are expected to be familiar with the classificationof isolated singularities of complex functions.
・Students are expected to be able to calculate the Laurent expansion of basic complex functions.
・Students are expected to be able to apply the residue theorem to the calculation of definit integrals.
