On 9.6.rc0 :

sage: sageobj(exp(i*x)._maxima_().demoivre())
cos(x) + I*sin(x)

BTW :

sage: exp(i*x).demoivre()
cos(x) + I*sin(x)

HTH,

exp(i*x).demoivre() works in Sage 9.5 and higher versions, but not in Sage 9.4 and lower.

Does the following work for you?

sageobj(exp(i*x)._maxima_().demoivre())
