- ColinWright 11y agoWhat do you want to graph? The first expression, A1, is: sum_{x=1}^{oo} 1/x If you convert that into a function: S(n) = sum_{x=1}^n 1/x then you'll find that S(n) ~ ln(n)-c where c is a constant. You can graph these sorts of things at Wolfram Alpha, or even just type the expression into Google and often you'll get something useful. Here's an example: https://news.ycombinator.com/item?id=9393392 https://news.ycombinator.com/item?id=9393392
- bengali3 11y agoThanks, in my messing around with WA, I wasnt getting a chart using the limit function, but now i realized I wanted the summation. I havent done much graphing online. TBH I was just curious how the graphs looked taking the positives and negatives independently. sum_{x=1}^{oo} 1/x vs sum_{x=1}^{oo} (-1)1/x vs sum_{x=1}^{oo} (-1)1/(x+1)
- ColinWright 11y agoI suspect you have problems there with asterisks for multiplication. Edit it to use dot instead of star, then I might be able to reply sensibly.
