Hi, i got a "report a problem" comment about how
simplify/full_simplify works. I think this could be sent to maxima
upstream?
Well, here is the (rather educational) example:
sage: a=(sqrt(6)-sqrt(5))^-1
sage: a
-1/(sqrt(5) - sqrt(6))
sage: a.full_simplify()
1/(sqrt(2)*sqrt(3) - sqrt(5))
sage: a.simplify()
-1/(sqrt(5) - sqrt(6))
----
yet, sympy which gives what the reporter expected:
In [3]: a=(sqrt(6)-sqrt(5))**-1
In [4]: a
Out[4]: 1/(6**(1/2) - 5**(1/2))
In [5]: simplify(a)
Out[5]: 5**(1/2) + 6**(1/2)
In [7]: pprint simplify(a)
------> pprint(simplify(a))
