This is the first lesson in the series on Matrices for the Year 11 General Maths course (VCE). I love matrices and this video shows you why. An introduction to the easiest topic in Mathematics looking at rows, columns, elements, what makes a matrix square and so much more. Lots of worked examples with easy to understand explanations makes this a video worth watching!
This is the second video in the General Maths series looking at Matrices. Having spent some time looking at the basics of matrices, I look at how we can use a matrix to describe a real world (practical) situation. Looking at the idea of a network diagram I use a matrix to represent the network diagram and discuss how we can interpret various parts of the matrix. There aren't many examples in this video, but there is a great explanation!
Adding and subtracting matrices is such an important skill! Walking down the aisles of the supermarket just wouldn't be the same without the need to add and subtract a matrix or two. Hold on. Perhaps it's not important for day to day to life, but it is important in this General Maths course! The matrices module continues with the first of a series dealing with operations on matrices. This one looks at addition and subtraction of matrices. I look at the conditions which allow you to add and subtract matrices with a number of worked examples. All explanations are clear and easy to understand and delivered with my own quirky style.
Adding another video to the General Maths series looking at matrices. What a video I have for you today! This one looks at how to multiply a matrix by a scalar. I explain what this means and use a number of worked examples to show you how simple a process this is. When things get tricky, I show you how to use the CAS too.
This is the next video in the series on Matrices for the Year 11 General Maths course (VCE). In previous videos I've looked at how to add, subtract and multiply a matrix by a scalar. Now it's time to look at some matrix multiplication. I look at how we can tell if two matrices can be multiplied (and are hence defined) and how to perform the multiplication. There are lots and lots of examples which are clearly explained and will allow you to smash this topic.
Continuing on with the series on Matrices, we now look at how we can apply Matrices to real world situations. This video is part of the Year 11 General Maths Units 1 and 2 course but is applicable to all courses the world over! I am asked all the time how Maths is relevant to real life. This video gives you a couple of examples of how to multiply matrices together to give real world information. It also explains about summing matrices and what they are used for.
This is the next video in the series looking at matrices and their applications in the General Maths Units 1 and 2 (Year 11) course. This is another wonderful video showing the practical applications for matrices. I look at how we can model networks using matrices and move on to looking at communication networks by looking at one-step and two-step communications. There are a few examples which are explained in my own unique style of teaching!
This is another video in the General Maths Units 1 and 2 (Year 11 VCE) which looks at the topic area of matrices. Building on the work we have done before we find out why we can't divide matrices. This video shows you the tools which will allow us to (sort of) divide matrices. I introduce the identity matrix and the inverse matrix. This video leads into the next video and is really important for the rest of the course. There are a number of worked examples all explained in my easy understand way.
Have you ever wanted to send encrypted messages but didn't know how?! Well, this video is going to show you how using the wonders of matrices. This video is another in the matrices series for the Units 1 and 2 General Maths series (VCE). I take a look at how we can use matrix multiplication to send encoded messages using a simple cypher and the mathematics we have been looking at before. This video builds on the previous video where we looked at the Identity and Inverse matrices and shows how we can use them (with the CAS) to encode and decode messages. Let the spy school training begin!
In previous videos I have looked at how to solve simultaneous equations using substitution, elimination and graphically. These are all pretty involved - which is why it's awesome that you can solve simultaneous equations using Matrices. Having spent some time looking at matrices, this video is going to make life much, much easier! The video is part of the Year 11 General Maths Units 1 and 2 course for VCE. The video has a number of worked examples where I explain the theory to ensure that you understand how to do this awesome method of solving simultaneous equations!
