Hey there,
I have a matrix [ [1, 1], [0, s] ]
I'm supposed to find the eigenvalue (and -vector) of the matrix...
I end up with something like...
(1-x)(s-x)-1 = s-x-x*s+x^2-1 = 0
Okay, so is there any way to make this more simple?
Because, when i start making vectors, it gets quite unhandy...
Maybe it is just supposed to be unhandy?
Uhm, I mean, the above equation is okay, but - when I try to find x it gets really complicated.
This was by the way the first task in a test without calculators...
Thanks for taking a peek at it...
