# Thread: Sigma Sums In Excel

1. ## Sigma Sums In Excel

Is anyone familiar enough with excel to use it to find the sum in of sigma notation when "n" is large?

$\Sigma^{40}_{k=1} \sqrt\frac{3k-3}{4}$

Something like this?

Hey alane1994.

What is stopping you from creating a formula, doing a fill-down and then using the SUM function in Excel?
