This function returns the sum of a power series.
SERIESSUM(x, n, m, coeff)
This function has these arguments:
Value to evaluate in the power series
Power to which to raise x
Step by which to increase n for each term in the series
Set of coefficients for the series (the values of a1, a2, ... ai)
The power series formula is:
where x, n, and m are the similarly named arguments and a is the coeff argument.
Accepts numeric data for all arguments. Returns numeric data.
