How do you simplify $\frac{1}{1}+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{100}$ or maybe a generalisation, like $\sum_{n=1}^{x}\frac{1}{n}?$ I don't know any way to do this so far. I've tried to split it into partial fractions, but was not able to do it. Any form of simplification would be fine.

There is no closed formula for your sum. You can find more information here: http://en.wikipedia.org/wiki/Harmonic_number · 3 years, 5 months ago
