@Everyone: I have added a separate heading towards the end of the wiki page. I would have done so yesterday but my internet had given up on me yesterday.
Anyway, a few things I'd like to mention before you read it. First, I did not read the existing wiki page before adding content to it. This I primarily did so that I do not get influenced by the content already mentioned on the wiki page. I will read the existing page now and then we can work on merging the solutions that arise from the discussion. Second, I believe that there were quite a few confusions related to the working of the CoordSys class and the RefFrame class. I have tried to discuss that issue a bit as well. Then, I have tried providing a mock session as well. The point about Euler angles confused me so I have not incorporated that in the additions to the wiki page. @Stefan : Could you explain in a bit more detail how exactly is the frame C rotated *wrt* to frame A. If I understand Euler angles correctly, then two frames first need to be aligned and then rotation if performed on one of the frames. But in this case, frame A and C aren't aligned. So, what exactly does saying 'wrt A' mean in the present context? -- You received this message because you are subscribed to the Google Groups "sympy" group.
