InverseSeries
InverseSeries[s]
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.

Find the series for the inverse of the function represented by an explicitly specified series:
| In[1]:= |
| Out[1]= |  |
Invert again to get back the original function:
| In[2]:= |
| Out[2]= |  |
