Quelles sont les valeurs propres de la matrice suivante, définie pour tout n≥3n\geq 3n≥3 par :An=(cos(log(n))cos(log(n2))⋯cos(log(nn))sin(log(n))sin(log(n2))⋯sin(log(nn)))A_n=\left(\begin{array}{llll} \cos (\log (n)) & \cos \left(\log \left(n^2\right)\right) & \cdots & \cos \left(\log \left(n^n\right)\right) \\ \sin (\log (n)) & \sin \left(\log \left(n^2\right)\right) & \cdots & \sin \left(\log \left(n^n\right)\right) \end{array}\right)An=(cos(log(n))sin(log(n))cos(log(n2))sin(log(n2))⋯⋯cos(log(nn))sin(log(nn))) I solved itMark it doneAdd to my listKeep it in your listI like this problem2 likesLiked byCypress@cypressCatalpa@catalpaShow related problems0No related problems yet.Solutions1Reveal solutionsAre you sure? Give it a try first.Solution by Ancient Tree · translated by CatalpaDiscussions0 useful votesC’est une question piège. La matrice n’est pas carrée, donc la notion de valeurs propres est mal définie.
