sage: t
tan(1/2*arctan(12/5)) sage: t.trig_simplify() sin(1/2*arctan(12/5))/cos(1/2*arctan(12/5)) sage: n(t) 0.666666666666667 But trig_simplify couldn't get 2/3. Maybe there is a fancier command that will do it? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
