takes the series s, and gives a series for the inverse of the function represented by s.
InverseSeries[s,x]
uses the variable x in the inverse series.


InverseSeries
takes the series s, and gives a series for the inverse of the function represented by s.
InverseSeries[s,x]
uses the variable x in the inverse series.
Details

- InverseSeries performs "reversion" of series.
- Given a series
, InverseSeries[s,x] gives a series for
such that
.
- InverseSeries can be applied to any SeriesData object with the appropriate structure, whether or not it has been generated by Series.
