Matrices II
Further Mathematics: Units 3 and 4
Introduction
Recap of past learning
RECAP: What are simultaneous equations
RECAP: Multiplying a matrix by its inverse
RECAP: Turning simultaneous equations into matrix form
Not all equations have crossing points
Inconsistent, dependent or one solutions
Example
Example 2
Not all matrices are 2x2!
How is this used in the real world?
Summary
This video is part of the Year 12 Further Maths course and the Matrices module. Having explained in a previous video how to find the inverse of a matrix, I now look at how we can use the inverse to solve simultaneous equations. I recap what it means to solve equations and what it means to have one solution, no solutions and infinite numbers of solutions. There are lots of worked examples which are explained in an easy to understand way.
