Dec 18	accepted	Find eigenvalues and eigenvectors: strange case
Dec 17	comment	Find eigenvalues and eigenvectors: strange case I have solved my doubt :) but I have an other question: the book says also that normalized eigenvectors are $v_1=\frac{1}{\sqrt {2m} }(1,1)^T$ and $v_2=\frac{1}{\sqrt {2m} }(1,-1)^T$.. why there is $\sqrt{m}$? thanks a lot
Dec 17	comment	Find eigenvalues and eigenvectors: strange case Thanks but my book says that the form of eigenvalues is $\lambda=\omega^2$.. how can I find it?
