Representation of Formal Power Series
Formal power series are procedures that return the coefficients of the power series they represent. Thus name⁡i is the coefficient of xi in the series called name.
The values of the coefficients are saved using a remember table, so all computed coefficients can be seen via op(4, op(name)).
The actual procedure is identical for all power series; the only differences are the general term and the values that each remembers.
The general term of the power series can be obtained via name(_k) .
Note: that each intermediate power series created in a calculation should be named.
Compute the series f^e .
logf ≔ powlog⁡f:
elogf ≔ multiply⁡e,logf:
result ≔ powexp⁡elogf:
