Sigma - Is this right?

Hey Lizzie:
No, the capital sigma is not used exclusively for Riemann sums. It is used in Riemann sums, though, because you're adding up a bunch of rectangle areas.
It is used to indicate summation from some point, say n=1, to some other point, maybe infinity, maybe something finite.
For instance, let's say we wanted to add up all the numbers from 1 to 100:
we could write this as:
\(\displaystyle \sum_{n=0}^{100}n=1+2+3+4+....+100\)

Well, out of two and a half pages of work and 10 problems with 2 hours to do them, I only FULLY understood the first page... That's how bad. My problem is that I got good grades in the first half of the semester because I already knew it before college, and then the second half I had to teach myself because it's an online course with NO interaction. That's where I started to fail and now I am going to have to retake Calculus. That's ok, tough because I wouldnt want to go on without fully understanding Calc. I'd just fail next year as well if I did that.
