### Course description and aims

The subject of this course is complex analysis. Complex analysis is the calculus of complex-valued functions of a complex variable. After reviewing several basic properties of complex numbers, we explain the differentiability of complex functions (holomorphy) and differentiable complex functions (holomorphic functions). Finally, we explain complex line integrals, Green's theorem and Stokes' theorem. In addition, as part of complex analysis, we review contents of [Calculus I / Recitation] and [Calculus II]. This course will be succeeded by [Applied Mathematics for Engineers Ib] in the second quarter.
Complex analysis is an absolutely essential mathematical basis of science and engineering. The aim of this course 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 the differentiability of complex functions.
・Students are expected to be familiar with elementary functions as complex functions.
・Students are expected to be able to calculate basic complex line integrals.
・Students are expected to understand the Green's theorem and Stokes' theorem, and be able to apply them to a calculation of an integral.

### 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.
