Yes that was also the next question in the exam paper I did, worked out perfectly at the end
Hi Bob thanks a lot for all the effort. I had no idea how to multiply more than 2 matrices so I tried doing all 3 at once...
and you should find that inverse A = E3.E2.E1
Never mind, bobbym was faster.
You multiplied the matrices incorrectly
Hi Bobbym any idea where I made a mistake?
which can be inverted.
Hi all. I think i'm making a mistake somewhere as the matrix I get after multiplying doesn't seem to be invertible and the next question is to find A^-1. Is this the right way to do this?
