Course description
Differential equations are used in describing phenomena and motions in various sciences, and especially in the field of science and engineering, their analysis is indispensable. In recent years, computers often deal with differential equations, but since the computer contains errors, some theoretical basic knowledge is required to judge whether the obtained solution is reliable or not. In this class, you learn "solving method" of typical ordinary differential equations. It is generally difficult to find all solutions of a differential equation. However, finding a suitable solution, we can often prove that there is no other solution or can obtain the other solutions by using the solution. In particular, concerning the class of linear differential equations, it is known that we get all the solutions as a linear combination of a finite number of fundamental solutions. In order to learn such a fact after this class, I will explain the first step of finding solutions.
Purpose of class
Natural phenomena can be modeled in terms of differential equations. The most of such equations are nonlinear. We can regard a nonlinear equation as a linear equation by approximating the solution locally. In this class, we will learn how to solve linear differential equations and nonlinear differential equations which can be reduced to the linear one.
Goals and objectives
  1. To understand relationships between differential equations and various sciences.
  2. To learn how to solve typical differential equations of 1st order.
  3. To learn how to solve linear differential equations with constant coefficients.
