RE: X^(1/3) plots differently than the cubic root of x
x^(1/3) is not the same as the cubic root of x, most CAS I know define x^(1/3) as the principal branch in the complex plane for x negative, this is like this since the beginning in Giac/Xcas, and there is no reason to change that, considering that the HP4x series use the same definition.
