From Confused to Confident – One Video at a Time.

Logarithms and Log Transforms

General Maths Units 1 and 2

This video is another in the Variation series for the Year 11 General Maths course. Looking at logarithms, I explain what a logarithm is and how it allows is to manage large numbers by making them "smaller". I look at examples of transforming numbers into logs (and back again). I then look at logar…

Data Transformations (Squared and Reciprocal)

General Maths Units 1 and 2

Continuing looking at Variation (forming part of the Year 11 General Maths course), this video builds on the work from the previous videos and looks at how we can transform data. Not all data will present in a nice straight line. Much of it will be curved. Being able to transform data which is curv…

Applications of Matrices

General Maths Units 1 and 2

This video continues the series relating to Matrices (forming part of the Year 11 General Maths course). In this video I look at how we can apply all the learnings we have from the past videos to real world application style problems. There are a number of worked example explained in an easy to und…

Using Recursion with Transition Matrices

General Maths Units 1 and 2

This video continues the series relating to Matrices (forming part of the Year 11 General Maths course). In this video I look at how we can use recursion with Transition Matrices. We know that states will change. Using Recurrence Relationships we can find one state from the previous. But this isn't…

Introduction to Transition Matrices

General Maths Units 1 and 2

This video continues the series relating to Matrices (forming part of the Year 11 General Maths course). In this video I look at the important topic of Transition Matrices. These are used to help us model and track changes from one state to another in real world situations. I look at what it means …

Minimum Spanning Trees and Greedy Algorithms

General Maths Units 1 and 2

This is the final video in the series and looks at some greedy algorithms to help us find minimum spanning trees (and, as extension, shortest path). I look at how to use Prim's Algorithm, Kruskal's Algorithm to find the minimum spanning tree and Dijkstra's Algorithm to find the shortest path. This …

Predicting and interpreting from a linear model

General Maths Units 1 and 2

This video looks at how we can use a linear regression equation (or least squares regression equation) to predict values. It forms part of the Year 11 General Mathematics course for VCE Mathematics. I look at how we can use the CAS to find a linear regression line and show examples of how we can pr…

Fitting a linear model to the data

General Maths Units 1 and 2

This video, forming part of the Year 11 General Mathematics course, looks at how we can fit a model to some data. Using the CAS we can find the least squares regression line and pearsons correlation coefficient to help us predict values we might have. I look at how to use the CAS effectively to fin…

Collinearity

Specialist Maths: Units 3 and 4

This is the fifth video in the series relating to Vectors as part of the Year 12 VCE (Units 3 and 4) Specialist Mathematics course. This content is important all over the world! Looking at what Collinearity, I explain what it means to be collinear and how we can use vector methods, to show that thr…
