Hi all How do I demonstrate that a 3x3 Jordan block with diagonal values equal to β equals: β^n nβ^(n1) 0.5n(n1)β^(n2) 0 β^n nβ^(n1) 0 0 β^n For n=1,2,3 and so on? (and sorry for the poor notation, I can't work out how to write it more clearly). Thanks in advance for your help. I've been going around in circles with this one.

I have substituted in the values n= 1, 2, and 3 and it the equation works. But I cant work out how to prove it for k and k+1 without just substituting them in directly. Perhaps this is right and I shouldn't try to overcomplicate it! Thanks!
