Hi,

I'm trying to enter a simple Sum function in Excel...by sum function
mean the math notation of a capital case Sigma

basically, I want to compute Sum (d)(L-x) for all values from x=0 t
x=L. How can I enter this formula in excel? Thanks for any help o
advice anyone might have! -Ti
 
Are both d & L an Array of numbers, or are they just constants? If they are
just constants, I believe the equation would be
d*L*(1 + L)/2
