SERIESSUM

Given parameters x, n, m, and a, returns the power series sum a1xn + a2x(n+m) + ... + aix(n+(i-1)m), where i is the number of entries in range `a`.

 

Sample Usage

SERIESSUM(1,0,1,{FACT(0),FACT(1),FACT(2),FACT(3),FACT(4)})

SERIESSUM(A2,0,2,B2:B10)

Syntax

SERIESSUM(x, n, m, a)

  • x - The input to the power series. Varies depending on the type of approximation, may be angle, exponent, or some other value.

  • n - The initial power to which to raise x in the power series.

  • m - The additive increment by which to increase x.

  • a - The array or range containing the coefficients of the power series.

Notes

  • Power series may be used to approximate various constants and functions, including e (Euler's number), logarithms, integrals, trigonometric functions, etc. However, this function is usually used for custom user-defined models.
