The result of such a series in general rings would contain expressions of the form sin(C), cos(D). Of course, in your case they would be immediately converted to RIFs, but the underlying general implementation would have to be over the symbolic ring. With the existing bias of mathematicians developing for Sage against symbolic expressions I'm pessimistic about an implementation in Sage.
