Hi all, I have completed the question up to part c). Using matlab, I have found the eigenvectors/eigenvalues but from there I am unsure as to how to find the solution which would comprise of the below frequencies. Also I am unsure as to how to go about part d).
Eigenvalues 0; 0; -0.382; -2.618;
Eigenvectors (corresponding) [1,0,0,0]; [0,1,0,0]; [0.3035,-0.1876,-0.7947,0.4911]; [0.4911,0.7947,-0.1876,-0.3035];
