Summary
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.
