• Deadline for Assignment 2 is extended to Friday
• A Matlab version of Chapter 9 of ``Differential Equations with Maple'' (PS,6 p.) is now available. It does not contain all of Chapter 9 in the book. You only have to read the introduction and the section ``Second Order Equations with Matlab'', and not the section ``Comparison Methods'' or anything after that in the book.
• Read corrections and hints for Assignment 2!!
• Exam 2 will be on Thu, Oct. 30. It will cover sections 8.1-8.4 (Numerical Methods) and sections 3.1-3.7 (2nd order linear equations, constant coefficients equations, method of undetermined coefficients, variation of parameters) in the textbook. You should also know the theoretical material in the section ``Reliability of Numerical Methods'' of Chapter 7 of ``Differential Equations with Maple'' (Matlab version (PS)). You don't have to know any Matlab commands for the exam. You don't have to know the Runge-Kutta method for the exam.
• Practice Problems for Numerical Methods are now available. Please do these problems to prepare for the exam. Note: I will not ask about numerical methods for second order equations or systems of ODEs in the exam.
• Using Matlab for Higher Order ODEs and Systems of ODEs is now available. Contents: Solving ODEs numerically and symbolically, plotting the solutions, phase plane plots, vector fields.
• Numerical Methods (PS, 16 p.), the Matlab version of Chapter 7 in ``Differential Equations with Maple'' is now available. Contents: Numerical solution ODEs using ode45 in Matlab; Euler, improved Euler and Runge-Kutta methods; controlling the eror in ode45, reliability of numerical methods.
• There is a page about Common Problems with Matlab. If you have trouble check this page before asking the tutor.
• Warning: the command close all sometimes causes Matlab to crash.
