[sage-edu] Restricting the field used when solving equations.

2009-12-10 Thread jason.t.stein
I am a high school teacher in Turtleford, SK Canada and am thinking about using sage in some of my teaching. The one problem I have right now is all of the complex roots found when solving an equation. Is there a way to restrict the returned solutions to the Reals? -- You received this message be

I prefer Polynomials than symbolic expression : sage: R. = PolynomialRing(QQ, 'x') sage: P = (x^2 + 1) * (x^2 - x - 1) sage: P.roots() # no root in QQ [] sage: P.roots(RR) # two roots in RR [(-0.618033988749895, 1), (1.61803398874989, 1)] sage: P.roots(CC) # four roots in CC [(-0.61803398874989
