SERIESSUMGiven 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`.
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.
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.
SUMSQ: Returns the sum of the squares of a series of numbers and/or cells.
SUMIF: Returns a conditional sum across a range.
SUM: Returns the sum of a series of numbers and/or cells.
QUOTIENT: Returns one number divided by another, without the remainder.
PRODUCT: Returns the result of multiplying a series of numbers together.
MULTIPLY: Returns the product of two numbers. Equivalent to the `*` operator.
MINUS: Returns the difference of two numbers. Equivalent to the `-` operator.
DIVIDE: Returns one number divided by another. Equivalent to the `/` operator.
ADD: Returns the sum of two numbers. Equivalent to the `+` operator.
