There is simplify_full() which should be safe for all expressions, and simplify_real() that assumes everything is real. Those two methods use our Maxima backend. The sympy backend has improved a lot, too. There's no easy way to get access to it, but something like this should work: sage: import sympy sage: f = sin(x/(x^2 + x)) sage: sympy.simplify(sympy.sympify(f)) sin(1/(x + 1)) In the case of f = sqrt(cos(x)^3 - 3*cos(x)^2 - cos(x) + 6), did you have any particular simplification in mind? I don't see anything obvious that can be done. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
