#### MathsCasts: Logic Circuits

(Swinburne Commons, 2011)

This screencast begins with explanation of 'OR', 'AND' and 'NOT' gates in a logic circuit, including what each gate looks like. An example is then given of drawing a logic circuit which contains several gates.

#### MathsCasts: Determinant of a 3x3 Matrix

(Swinburne Commons, 2011)

Example of finding the determinant of a 3x3 matrix by hand, together with explanation of the general method.

#### MathsCasts: Truth Tables

(Swinburne Commons, 2011)

A demonstration of how to set up a truth table for a Boolean expression, in the context of a particular example.

#### MathsCasts: Non Right-Angled Triangles

(Swinburne Commons, 2011)

This screencast gives explanation of two rules for finding unknown angles and/ or lengths of sides in any triangle: the Sine Rule and the Cosine Rule. Examples are then given to show how to apply each rule in practice.

#### MathsCasts: Graphing Factorised Polynomial Functions

(Swinburne Commons, 2013)

Looks at how linear factors to odd and even powers can help in sketching polynomial functions that can be factorised into all linear factors.

#### MathsCasts: Prime Factors

(Swinburne Commons, 2013)

We look at how to factorize a number into a product of prime factors, with several examples.

#### MathsCasts: Inverse Functions: Example 1

(Swinburne Commons, 2013)

Gives the definition and conditions for the inverse of a function to exist, and then applies this to an example the case of finding the inverse of a one-to-one function.

#### MathsCasts: Writing Composite Trigonometric Functions as Algebraic Expressions

(Swinburne Commons, 2012)

Several examples are given of rewriting composite circular functions, where the inner function is an inverse trigonometric function, as an algebraic function in terms of x.

#### MathsCasts: Visualising Solution of 3 Linear Equations in 3 Unknowns

(Swinburne Commons, 2012)

Examples are given of the visual interpretation of systems of 3 simultaneous linear equations in 3 unknowns for the case where there is a unique solution, an infinite number of solutions, and no solutions.

#### MathsCasts: Equating Complex Numbers

(Swinburne Commons, 2012)

The conditions for equality of complex numbers are given. An example of grouping and then equating real and imaginary parts of complex numbers on both sides of an equation to find unknown quantities is then given.
