Question

how to find eigen values of a 3*3 matrix?

Answer 1

Do you want the good way or the way they teach you in school?

Answer 2

good waY!

Answer 3

well good in a computational sense, it will not help you solve it by hand

Answer 4

the traditional way is det(A-lamda*I)=0

Answer 5

i know it but at the end i am getting the same eqn :
x1+x2+x3=5
x1+x2+x3=5
cant get the eigen vector...plz help mate!

Answer 6

What is the matrix?
