I can't get how to work with series. I do
sage: R.<t> = PowerSeriesRing(QQ)
sage: t^2
t^2
sage: sin(t)
but the last rises an error. I want to do usual manipulations like sin(t)/cos(t+2)^2.

Working with series
I can't get how to work with series. I do
sage: R.<t> = PowerSeriesRing(QQ)
sage: t^2
t^2
sage: sin(t)
but the last rises an error. I want to do usual manipulations like sin(t)/cos(t+2)^2.sin(t)/cos(t+2)^2.
