This is the first in a new series of videos looking at the Graphs module for Further Maths Units 3 and 4. Starting with the basics I take a look at how to find the gradient of a straight line. I look at positive, negative and zero gradients and how to use two different formulae to find the gradients. Lots of worked examples are done all explained clearly and related to the theory. This is THE video to watch if you want to understand how to find the gradient of a straight line.
This video is part of the Year 12 Further Maths course and looks at the general equation of a straight line. In a previous lesson we looked at how to find the gradient of a straight line. Once we know the gradient, we only need to know one coordinate and we can find the relationship to find the rest of the points on the line. This relationship is called the equation of a straight line. I look at a number of examples and explain them using easy to understand and clear theory.
This is another in the Further Maths series of videos looking at the Graphs module. Having looked at how to find the equation of a straight line in a number of ways, I take a look at how to sketch equations using the equation of a straight line in intercept form. This is one of the easiest ways of sketching a straight line graph using the intercept form of the equation. I look at a number of worked examples which are all explained using easy to understand theory.
This is another video for the Further Maths Units 3 and 4 course dealing with graphs. With the theory of straight lines already covered I look at how this can be applied to real world situations. Linear models looks at how we can take relationships in real life which are linear and model them mathematically. There are a couple of worked examples which are explained using clear and easy to understand theory.
This is another video in the Further Maths Units 3 and 4 series looking at straight lines. In previous years you will have looked at how to solve simultaneous equations using substitution and elimination methods. I look at using the CAS to solve simultaneous equations by drawing them on the graphical screen and using the system of equations function. There are a number of worked examples with clear instructions on how to use the CAS all backed by clearly explained theory. The final section of the video looks at how to solve using the substitution and elimination methods.
This video is another in the linear series for Further Maths looking at how we can apply the learning from past videos to solve more complex worded problems relating to Simultaneous equations. I use two examples (which seem to be the main type of questions) to frame and explain the theory in an easy to understand way. All with a little bit of humour and a lot of personality. I hope you enjoy the video.
