# SIGMA(FofN,from,thru)

Evaluates the sum of a series.

### Syntax

o_SIGMA(FofN,from,thru)
  FofN: scalar Text - function to be evaluated with argument "n"
  from: scalar number - lower limit of "n"
  thru: scalar number - upper limit of "n"
  return: numeric - the sum of terms F(n) for n=from through n=thru

### Usage

An arbitrary function of "n" can be evaluated for a series. This implements a standard "SIGMA" notation sum.

### Location

menu: veeos ==> Math ==> SIGMA

library: mathLib

### Example

o_SIGMA("n^2*(n-1)",3,5) = (9*2)+(16*3)+(25*4) = 166

### Notes

A very common operation for series is the sum of the various terms. This evaluates that product.
