I ran those numbers through on paper before too, but it never clicked that I could find the sum individually and add them together. Thanks for your help.
1. Homework Statement :
The following is a geometric series.
Determine whether series is converges or not.
For the series which converge, enter the sum of the series
\sum^{\infty}_{n=1}\frac{7^n+3^n}{8^n}
2. The attempt at a solution:
I've looked into calculating...
I completely agree except in this case: T.13 has left her problem untouched since her last post on May 1st, 3.5 months ago. It seems that by now she has either solved the problem or lost interest in it.
I was continuing her question b/c it is similar to one I have, which also deals with...
That's what I thought I was doing... well my think was that if it took the force dF for the particular sliver dy, then it would take dF * the height of each sliver (distance = y, from 0, the top, to 1, the bottom), and do that for every sliver dy.
Since the water level is equal to the top of...
