Start at the beginning.
What is a partial sum? What is meant by
I don't even know where to start for this question. If someone could help me with the first few steps, I would be very grateful!
If the nth partial sum of a series Sigma (infinite sum, n=1) is s(sub)n=3-n^(-n), find a(sub)n and the partial sum of a(sub)n
A partial sum is taking all integers (to infinity) plugging them into an equation, and adding each term together. I started with a table, and tried to find some sort of pattern by subtraction between each term, but got nowhere fast.
Ok, our variables are a bit different. On your sigma, my n=infinity, k=1, and a(sub)k=3-k2^(-k). The question asks me to find a(sub)k and the sum from k=1 to infinity of a(sub)k.
(Sorry, I don't know how to use online math notations at all.)
Edit: Wait a minute, I missed some of your post. Hold on.
Edit 2: Ok, so we agree on our definitions of partial sums, but this is an infinite sum, and I don't understand any more about the problem than what I started out with... Sorry if I'm being dense...
