### Course description and aims

Based on [Applied Mathematics for Engineers II a] in the third quarter, this course focuses on Fourier analysis and its applications. In particular, we expalin a method to solve differential equations by using Fourier series. First, we explain the classification of differential equations. Then we explain general strategies to solve differential equations by using Fourier series. Finally, based on such strategy, we explain the method to solve the heat equation, the wave equation and other equations by using Fourier sereis.

Fourier 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 Fourier analysis by an efficient way.

### Student learning outcomes

・Students are expected to understand general strategies to solve differential equations by using Fourier series.
・Students are expected to be able to solve the heat equation by using Fourier series.
・Students are expected to be able to solve the wave equation by using Fourier series.
・Students are expected to be able to solve the Dirichlet problem for the unit circle by using Fourier series.
