Question

How do you find if a 3x3 Matrix is Diagonalisable?

Answer 1

Where is joe?

I think u get 3 eigenvectors (li set) and make matrix with them as columns.

Then get S^-1 and show S^-1(your matrix)S is a diagonal matrix with eigenvalues of your matrix on the main diagonal.

If u can do that, then your matrix is diagonalizable.

(But Joe might have some better way).

Answer 2

AWh I know what you mean. I have no idea who Joe is. Cheers estudier (Again)
