Two n x n matrices A and B are called similar if there is an invertible matrix P such that B = P-AP. Show that two similar matrices enjoy the following properties. (a) They have the same determinant. (b) They have the same eigenvalues: specifically, show that if v is an eigenvector of A with eigenvalue 1, then P-lv is an eigenvector of B with eigenvalue l. (c) For any polynomial p(x), P(A) = 0 is equivalent to p(B) =...

4. Find the general solution by undetermined coethcies "+4y Sr +4sin(2). cos(2) +c2 sin(2r). SOLUTION: The homogeneous solution is +4-02 does match ga so we must multiply by z. So For the particular solution, Se Ae2 which does not match h. But B cos(2z)+Csin(2) Ae Br cos(2x)+ Cr sin(2r) (Bs cos(2x) )" = 0cm(2x)-,4B sin(2x)-4B2 cos(2z), Using ()"-f'g+2f's+is", we have Ca sin(2x)Osin(2r)+4C cos(22)-4Cz sin(2r). So plugging Vo in for y,...
