Dear all,
I just noted some strange behaviour with simplify_radical():
----------------------------------------------------------------------
| SAGE Version 3.1.2, Release Date: 2008-09-19 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: sage: var('a b c')
(a, b, c)
sage: ((a*b - 0.5*a*(b - c))/a).simplify_radical()
0
sage: ((b - 0.5*(b - c))).simplify_radical()
0.500000000000000*c + 0.500000000000000*b
Clearly, the second result should be the same as the first one, as 'a'
cancels out. Does anyone know how to avoid such mistakes and whether
it is advisable to use simplify_radical at all?
Cheers
Stan
