Problem with 3x3 3d rotation matrices logic - concatenation doesn't work as expected?

If M0 = C0 * X0 (rule 8), then X0 = Ct * M0 (your formula X0 = M0 * Ct is wrong).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
