2010-09-29 12:00:41 +0200	marked best answer	complex exponential/trigonometric This works for me in Sage 4.5.3: `sage: x = var('x') sage: t1 = cos(x) sage: t2 = e^(I * x) / 2 / I - e^(-I * x) / 2 / I sage: sageobj(t1._maxima_().exponentialize()) 1/2e^(-Ix) + 1/2e^(Ix) sage: sageobj(t2._maxima_().demoivre()) sin(x)` Perhaps there's a simpler way? I don't think we've wrapped Maxima's `demoivre` and `exponentialize` in Sage. They're documented here.
2010-09-25 21:36:07 +0200	asked a question	complex exponential/trigonometric Is there any command equivalent to the Mathematica's "TrigToExp" and "ExpToTrig"? Where should I look for general support on complex exponential/trigonometric functions?
