#### MathsCasts: Absolute Value: Less Than: Part 3

(Swinburne Commons, 2012)

Part 3: Shows how to solve absolute value inequalities, example abs(2x-1)<5

#### MathsCasts: Binary to Decimal Conversion

(Swinburne Commons, 2012)

Shows how to convert from a binary number to its corresponding decimal number. Two examples are given.

#### MathsCasts: Chain Rule or Not?

(Swinburne Commons, 2013)

Six short examples useful as preparation for implicit differentiation. Some require the chain rule, others are straightforward differentiations.

#### MathsCasts: The Equation of a Circle

(Swinburne Commons, 2011)

Starting with an equation quadratic in x and y, this screencast shows the general form of a circle, to which the equation has to be converted. It then shows how to complete the square in x and in y and how to read off the ...

#### MathsCasts: Even and Odd Rational Functions

(Swinburne Commons, 2012)

Shows how to check if a polynomial is even or odd, and extends this to a rational function.

#### MathsCasts: Absolute value: Greater Than: Part 2

(Swinburne Commons, 2012)

Part 2: Shows how to solve absolute value inequalities, example abs(1-2x)>-3

#### MathsCasts: Sarrus' Rule to Find the Determinant of a 3x3 Matrix

(Swinburne Commons, 2011)

This screencast demonstrates how Sarrus's Rule can be used to find the determinant of a 3x3 matrix. This is an alternative to the usual method of going via 2x2 sub-determinants.

#### MathsCasts: Logarithmic Differentiation: Handwritten

(Swinburne Commons, 2011)

This screencast explains how differentiation requiring combinations (or multiple uses) of the product, chain and quotient rules can be made simpler by using logarithmic differentiation. This method relies on log rules to ...

#### MathsCasts: The Multivariate Chain Rule

(Swinburne Commons, 2011)

Shows how to find a particular form of the chain rule that is needed, depending on the type of problem that is posed. Uses a tree diagram to develop the rule.

#### MathsCasts: Simplifying Compositions of Trig and Inverse Trig Functions

(Swinburne Commons, 2013)

Two examples of simplifying expressions of the form trig(inverse trig), using right angled triangles. The result is in algebraic form without trig functions.
