1. In general, any 3 by 3 matrix whose eigenvalues are distinct can be diagonalised. 2. If there is a repeated eigenvalue, whether or not the matrix can be diagonalised depends on the eigenvectors. (i) If there are just two eigenvectors (up to multiplication by a constant), then the matrix cannot be diagonalised.the desired solution is x(t) = 3e @t 0 1 1 0 1 A e At 0 @ 1 0 1 1 A+ c 3e 2t 0 @ 1 1 1 1 9.5.35 a.

This gives the two solutions. y1(t) = er1t and y2(t) = er2t.

As with the last section, we’ll ask that you believe us when we say that these are “nice enough”.Dylan’s answer takes you through the general method of dealing with eigenvalues for which the geometric multiplicity is less than the algebraic multiplicity, but in this case there’s a much more direct way to find a solution, one that doesn’t require computing any eigenvectors whatsoever.
