Yes, there are lots of book: 1) Elementary Linear Algebra (2nd Edition) (very nice book) Lawrence E. Spence, Arnold J. Insel, Stephen H. Friedberg: http://library.nu/docs/1AE3ONR9XD/Elementary%20Linear%20Algebra%20%282nd%20Edition%29 (which has a solution manual...

Thank you for your replying T(x,y, z) and T(X,Y,Z) in the new and old axes frame respectively. More generally, my second question is that if I have two matrixes (old and new), how can I calculate the rotation matrix between these two matrices? I have to mention that this rotation...

Hi, I have a rotated frame (new matrix, T(x,y, z)) and the original frame (old matrix T(X,Y,Z)). I want to use this formula to find the Rotation matrix: T(x,y, z) = R-1 T(X,Y,Z) R Is this equation right? how can I calculate R (rotation matrix) in ZYZ order in this equation? Thank You

because the energy of the tials functions are always more more than the ground state

How can I undrestand that an equation have real solutions? thanks

Dear Bavon Would u please help me to solve this problem too? thanks I am looking forward for ur reply. It is an emergency situation!
