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.
