Evaluates a power series.
Syntax:
SERIESSUM( x:Number, n:Number, m:Number, coefficients:Range or Array )
Returns the sum of the given power series for x.
n is the initial power to which x is raised, this being multiplied by the first value from the coefficients range of cells (or array) of numeric values. For each subsequent coefficient, m is added to the power.
Formula:
SERIESSUM = a1⋅xn + a2⋅x(n + m) + a3⋅x(n + 2⋅m) + … + aN⋅x(n + (N-1)⋅m)
