I don't think we've wrapped Maxima's demoivre and exponentialize in Sage. They're documented here. 2010-09-25 14:36:07 -0600 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?
