#### MathsCasts: Boolean Algebra: Example 1

(Swinburne Commons, 2011)

An example of using the laws of Boolean Algebra to simplify a Boolean expression, including use of De Morgan's laws.

#### MathsCasts: Karnaugh Maps for Two Variables

(Swinburne Commons, 2011)

In this screencast we look at how to set up a 2-variable Karnaugh map, followed by an example of simplifying a particular Boolean expression and simplifying its negation, using a 2-variable Karnaugh map.

#### MathsCasts: First Order Differential Equations: Separation of Variables 2

(Swinburne Commons, 2011)

This screencast illustrates the method of separation of variables for a medium-level first order differential equation: dy/dx=(2-y)/(1+x). Different ways of displaying the solution are discussed.

#### MathsCasts: Introduction to Linear Inequalities

(Swinburne Commons, 2011)

This screen casts contains an introduction to linear inequalities, including definitions and simple examples.

#### MathsCasts: How Does the Integrating Factor Method Work

(Swinburne Commons, 2011)

Explains the integrating factor method and gives a quick proof.

#### MathsCasts: Negating and Simplifying Switching Circuits

(Swinburne Commons, 2011)

Given a diagram of a particular switching circuit, we start by identifying a Boolean function to represent it. We then find the negation of the switching circuit and finally, the simplest possible expression for it using ...

#### MathsCasts: Algebra: Removing Brackets

(Swinburne Commons, 2011)

Worked example showing how to remove brackets of the form a(b+c)

#### MathsCasts: Boolean Algebra: Example 2

(Swinburne Commons, 2011)

Example of simplifying a Boolean expression using Boolean Algebra, with particular emphasis on using the rule (p+q)(p+r)=p+qr to help simplify an expression that otherwise would have involved extensive and time-consuming ...

#### MathsCasts: Gaussian Elimination

(Swinburne Commons, 2011)

Demonstration of the principle of solving a system of linear equations using Gaussian Elimination, with reference to a specific example with 3 equations and 3 unknowns where there is a unique solution.

#### MathsCasts: Algebra: Real Life Problems

(Swinburne Commons, 2011)

This screen casts demonstrates worked examples of where the algebra skills already learned can be used in real life.
