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

(Swinburne Commons, 2011)

Explains the integrating factor method and gives a quick proof.

#### MathsCasts: Logarithmic Differentiation: Typed

(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: Vector Components

(Swinburne Commons, 2011)

Explains briefly the concept behind vector components - that one vector is written as the sum of a component into a direction of another, plus the perpendicular vector. Then an example is worked through.

#### 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: 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.
