Hi everybody! Strange things do happen! Mathematica4s ability to simplify equitations containing square roots seems to be quite weak. Perhaps I just do not know enough about these things, but I did read the manual. An example: Sqrt [ R ( R - x ) ] Sqrt [ ( R - x ) x ] / ( R x - R^2 ) equals Sqrt[ R / x ], but I can4t get Mathematica figure that out. I tried PowerExpand, Factor, Collect, Simplify and almost everything else in various orders. Nothing worked! What can I do? I do appreciate every helpful hint. Thank you very much.
