授業概要
We first learn in calculus that derivatives can be used to represent the rate of change of one variable (height, temperature,....) with the change in another (space, time,...).  At the simplest level, a differential equation is just an equation containing a derivative.  Consequently, any physical phenomena that involves a rate of change leads to a differential equation, and an understanding of solution methods for differential equations is therefore essential for studies of phenomena in physics, biology, chemistry and engineering.

This course focusses on the solution of ordinary differential equations (those depending on a single independent variable) and as well as teaching solution methodologies, also includes various applications of the methods to problems from the natural sciences and engineering.
授業の到達目標 Learn methods that can be used to solve a wide variety of ordinary differential equations

Learn how some ordinary differential equations can be derived from modelling physical phenomena
事前・事後学習の内容 Students should review their notes after every class.
