Summary
This video is part of the Further Maths Units 3 and 4 course and the Matrices module. This video looks at how to find the inverse of a matrix. It explains what the inverse of a matrix is and what it can be used for. I look at how to find the determinant and what it means where it is zero. I also look at how to use matrices for the solution of simultaneous equations. There are lots of worked examples which are all explained in an easy to understand way.
