I didn't know whether I should put this here or under Random.
I'd like to write a program for my TI-83 that calculates sigma notation. Unfortunately, I have no idea how (which is frustrating, because I'm usually pretty good with writing programs for my Honors Pre-Calc class).
If anyone could shed some light on the subject, or perhaps just provide me with the code for such a program, I'd be very appreciative.
Some of you know about The Cody Foundation (www.codyfoundation.com). (To those of you that don't, Cody is the son of my best friend who died of cancer at 6-1/2 years old). We are working on our next fundraiser, which will be the middle of February.
