This is the first video in the General Maths series looking at Linear Relations. You have been substituting into equations and expressions since Year 7 and so this video will serve as a recap on what it is you need to do. There are some worked examples and a recap of BIDMAS. I look at where you might make mistakes and explain it all in an easy to understand way.
This the next video in the General Maths series on Linear Relations and Equations looking at constructing a table of values. We have met equations before (in every year so far!). But we normally only substitute one value into the equations and get one value out. What happens if we put in a lot of values? Well, we get a lot of values out! To keep all the data sorted and readable, we can use a table. This video shows you how to create a table of values using pencil and paper methods and using the CAS. Lots of examples all explained in my unique fashion.
This is another video in the General Maths Linear Relations and Equations chapter looking at solving linear equations with one unknown. You may think you've been taught algebra before, but I don't think you'll have been taught it in quite this way! Kissing, bunk beds, prison guards ... it's a different way of seeing things and it will help you be the boss of linear equations. I start with the simple stuff and show you how you can unpack the easiest of linear equations with one unknown. Later videos show you how to do more complex things. There are a few worked examples and I show you how to use your CAS too.
This is another video in the General Maths course looking at Linear Relations and Equations! Don't you just hate the English language? It's so confusing! We use words when we can use numbers. Letters when we can use numbers. Well, this is the video where I show you how to be less confused when turning worded questions into equations. There are a number of worked examples where I show you that it's OK to choose any letter you like to stand for a number. I break each problem down in my own unique style and show you that you can be the BOSS!
This is another video in the series looking at Linear Relations and Equations. Have you ever wondered what a literal equation is? Nope? Me either really ... but if you're being made to ... then this is the video for you. Literal equations are equations where there isn't just a numerical answer. Normally we solve equations to find a numerical answer. Literal equations will have numbers and letters. Some times they have only letters! This video will show you how to solve literal equations with some worked examples and lots of explanations. Try me. Trust me. I've got your back
Following on from a previous video where I looked at setting up linear equations in one unknown, I am back and throwing in another unknown. Worry not! This video (which is a part of the VCE General Maths course on Linear Equations and Relations) is everything you need to smash your understanding to the next level. I look at an example of how to extra information from a question and how to use it to construct and equation. I then go on and solve the equation. All of this is done with my unique and easy to understand style.
This is another video in the General Maths (Year 11) course looking at Linear Equations and Relations. This is marked as an optional video but the good news is .. you already know the content and how to use the CAS so why not give it a go. I take some time looking at how to solve equations with square and square roots which, again, can be solved using the CAS! Lots of worked examples are used and the explanations are easy to follow and a little humourous.
Powering through the videos for the Year 11 (VCE) General Maths Units 1 and 2 course looking at Linear Equations and Relations. It doesn't get any better than this! Having already looked at how we can use the CAS to solve equations and using "by hand" methods to solve, we find that the CAS can also transpose equations for us. It's exactly the same as the things we have already been doing. So, I take the time, in this video, to look at how to use the CAS to transpose formulas and then solve them. There are a number of worked examples all explained in my unique style. Seriously ... I've got your back. So, why not try me.
Have you ever wondered how to find the point of intersection of two lines? Well, this is the video for you! Part of the General Maths series for Linear Equations and Relations, it will show you all you need to know about finding the point of intersection of two linear graphs. I take some time to review past learning and then look at what makes a graph linear. I place two linear graphs on the same set of axes and find that for many of them, they meet at a point of intersection. This point can be found using the CAS and interpreted. So much excitement in just one video.
This is another in the General Maths series for Year 11 Maths looking at Linear Equations and Relations. Solving simultaneous linear equations algebraically is a really big part of Mathematics and this video shows you how to do it using both substitution and elimination methods. I use a number of worked examples and show you how to master this. The video is a little long ... but it's due to me doing a number of worked examples. The explanations are clear with a smattering of wit.
Having shown you how to solve using pencil and paper methods, I now show you how to use the "Solve a system of equations" function on the CAS! This video is another in the General Maths series looking at Linear Equations and Relations for Year 11 here in Australia - but it's also helpful for all Maths courses! As this is a CAS course, it's important to know that we can use the CAS to find the solution to simultaneous equations! This video looks at how to use the Ti-Nspire to solve systems of equations. A number of examples are used and they are all explained in an easy to understand way.
The videos for linear equations and relations are almost complete but it wouldn't be complete without showing practical examples of how to apply the solving of simultaneous equations. Hence, welcome to this video on practical applications of simultaneous equations. It doesn't get any more exciting than this. I look at three examples and show you how to extract the two equations you need, and then solve them by hand and checking with the CAS. I fully explain the questions in an easy to understand way and hope you have some fun whilst learning.
