{{{
[00:12] <jason--> sage: t = QQ[['t']].0
[00:12] <jason--> sage: 1/(1-t)
[00:12] <jason--> 1 + t + t^2 + t^3 + t^4 + t^5 + t^6 + t^7 + t^8 + t^9 +
t^10 + t^11 + t^12 + t^13 + t^14 + t^15 + t^16 + t^17 + t^18 + t^19 +
O(t^20)
[00:12] <jason--> but log(1+t) doesn't work, for example
[00:12] <jason--> should it?
[00:12] <craigcitro> in principle, yes. :)
[00:13] <craigcitro> see if (1+t) has a log method ...
[00:13] <jason--> and sin(t), cos(t), etc.
[00:13] <jason--> so maybe a fallback method that calls for a taylor
series?
