ComposeSeries[series1,series2,]

composes several power series.

Details

  • ComposeSeries[series1,series2,] effectively replaces the variable in series1 by series2 and so on.
  • Two series can only meaningfully be composed when the point about which the first series is expanded corresponds to the limiting value of the second series at its expansion point.

Basic Examples  (2)Summary of the most common use cases

Compose two power series:

Out[1]=1
Out[1]=1
Out[2]=2

Properties & Relations  (2)Properties of the function, and connections to other functions

ComposeSeries generates the series of composition of functions:

Out[5]=5
Out[6]=6

Coefficients of the composition of series can be computed using BellY:

Out[1]=1
Out[2]=2

Possible Issues  (1)Common pitfalls and unexpected behavior

The limiting value of the second series must coincide with the expansion point of the first series:

Out[1]=1
Out[2]=2
