Chapter 2 - Numerical Methods

Worksheets for the 3 numerical methods in chapter 2. Use these to help with by-hand calculations.

Calculator programs for the numerical methods.

The directions for using both of these two programs are the same. See the Euler program for detailed directions.

Euler Method Example 1. given out 9/24/08
Euler Method Example 2. given out 9/24/08

Improved Euler Method Example 1. given out 9/29/08
Improved Euler Method Example 2. given out 9/29/08

The Taylor Method is not in your textbook.
Taylor Method 2nd Order Example. given out 10/6/08
Taylor Method 3rd Order Example. given out 10/6/08
Taylor Method 4th Order Example. given out 10/6/08

The various methods each have their own advantages. Some are quicker to compute than others. Some have a higher accuracy with fewer steps. See a comparision of the methods to help you determine which one you prefer.

Tests

The following is the solution for Test 1 problem number 9 (the oven question)

The following is the solution for Test 2 problem number 11 (the non-homogeneous question)
When your characteristic equation has complex roots (ie: you get imaginary lambdas), there are several ways to solve for y.

Chapter 4

How to transform a differential equation of order 2 or more into a system of first order differential equations. given out 11/5/08.
An example on how to solve a 2-dim system of 1st order differential equations. given out 11/5/08

Chapter 7

The detailed way to get the LaPlace transform of t^a where a is any real number greater than -1. This handout also includes information on the Gamma Function, which is basically a fancy name for n!. given out 11/17/08.
