Hey guys,
I have a problem that I am doing but I am stuck.
Is the matrix for part A simply A= 2 -2 0
-2 1 -2
0 -2 0 ????
I am stuck on part B, as doing lambda*I -A gives a rubbish determinant answer, or I am just doing it wrong. It would be great to have pointers on the remainder of the question as well.
Help would be much appreciated.
