So I trying to find a 2 * 2 Matrix M where but where does not = I
So for n = 1 M=I,
for n = 2
for n = 3
for n = 4
These are just a few examples I found using algebraic methods however I can not find an example for n = 5, is there a possible reason for this?
Futhermore can you find a 2 * 2 matrix M where and ?
Also is there a better way to attempting these problems than working through several simultaneous equations?
Thanks
