If you're unable to derive the general case immediately, perhaps you could gain some insight in the problem by checking it for the thew first values of n (1,2,3).
Wassup,
We're doing eigenvalues in class atm (got a test tomoz), and though I can find them for finite matrices, I'm struggling with ones which extend to the nth row:
e.g:
Find the eigenvalues of the nxn matrix:
1 1 ... 1
1 1 ... 1
...
...
...
1 1 ... 1
Any help at all is appreciated.
