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(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 x is raised in the power series.

  • m – The additive increment by which x is increased.

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


  • 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.
