Course description
This course corresponds to “the specialized fundamental course" (elective).

Objectives:
Basic subjects such as mechanics learned at the Faculty of Engineering, we can see many expressions using differential equations as a method of describing the phenomena. We will use a method to stress a physical interpretation of mathematical formula, discussing the characteristic of the differential equations to describe physical phenomena. Especially, we will emphasize the characteristic of partial differential equations.

Resume:
As to the second order, linear differential equations, choosing wave and heat conduction equations as examples, which are basics in physics, analytical solving methods and numerical solving ones will be learned. Especially, classification of standard forms by the change of variables, separation method of variables as a powerful analytical solving method, and approach to the in-homogeneous equation will be acquired.
Expected Learning
Physical mathematics is a base of the special field of study at the Faculty of Engineering. In this lecture, we aim at making students understand main partial differential equations describing physical phenomena. Corresponding criteria in the Diploma Policy: See the Curriculum maps.
Course schedule
First Lecture - Introduction and ordinary/partial differential equations: Examples of partial differential equations and review of ordinary differential equation. Then, we will explain what partial differential equations are.

Second Lecture - First order partial differential equation (I): As to first order partial differential equation, general solutions using such as total differential and Lagrange equations will be explained.

Third Lecture - First order partial differential equation (II): The later part of the first order partial differential equation will be explained.

Fourth Lecture - Classification of second order, linear partial differential equations: Classification of second, linear partial differential equations, hyperbolic, parabolic, and elliptic types, transformation to standard form using the change of variables will be explained.

Fifth Lecture - Derivation of second order, linear partial differential equations in physics: Partial differential equations will be derived. Deriving wave and heat conduction equations from real physical phenomena, their characteristics will be investigated.

Sixth Lecture - Variable separation method (I): Applying a variable transformation method to a couple of the basic second order, linear partial differential equations, transformation to a few ordinary differential equations will be learned.

Seventh Lecture - Variable separation method (II): The later part of the variable separation method will be explained.

Eighth Lecture - Summary of the first half.

Ninth Lecture - Two-dimensional wave equation (I): Wave equation as a partial differential equation will be solved by the use of separation of variables. Bessel's differential equation and expansion of orthogonal functions will be learned. In addition, we will make students understand superposition of solutions satisfying boundary conditions.

Tenth Lecture - Two-dimensional wave equation (II): The later part of the two-dimensional wave equation will be explained.

Eleventh Lecture - Laplace equation (I): As a steady state solution, Laplace equation will be treated. We will also investigate the characteristic of Laplace equation.

Twelfth Lecture - Laplace equation (II): The second half part of solution of Laplace equation will be given in our lecture.

Thirteenth Lecture - Eigenfunction expansion method: This method will be introduced in the case of inhomogeneous differential equation, and also variation of parameters will be learned.

Fourteenth Lecture - Supplemental lecture and practice

Fifteenth Lecture - Summary of the second half.

routine exam
Prerequisites
It is better to understand the contents of basic subjects such as related mathematics and physics etc. It is necessary to do preparatory study and review for the standard number
of hours.

Assessment/Grading
Five times of quiz in class (30%)
Two reports (10%)
Midterm examination (30%)
Final examination (30%)
Message from instructor(s)
Although it is better to remember mathematical formulae and rules etc., doing your utmost to clear their physical images is desirable, not sticking them. It is enough that to know the place in books to find the formulae etc.
Course keywords
Differential equation, separation of variables, expansion of eigen function, finite difference, special function.
Office hours
Just after the lecture or appointment determination at that time.
