Yes, it took me a few days to understand (I'm not an expert mathematician) but I understand already it. Because I did many tests, I don't remember exactly what errors I committed, but remember that some time had no effect the "Specify relative reference point" option, because I gave value 0 to the angle b, but not always.
Thank you very much for the explanation, it was a great help.
Best regards
