 Apr 27 asked Determining the Length of a Curve Using Partitions Apr 26 accepted Showing that $\cos\left(\frac{\pi}{5}\right)=\frac{1}{2}\phi?$ Apr 25 asked Showing that $\cos\left(\frac{\pi}{5}\right)=\frac{1}{2}\phi?$ Apr 25 comment If $m$ and $n$ are positive integers, then $(F_m,F_n)=F_{(m,n)}$. I understand now. :) Thanks, guys! Apr 25 comment If $m$ and $n$ are positive integers, then $(F_m,F_n)=F_{(m,n)}$. There's a step where he states that $(f_{n-m},f_m)=f_{(n-m,m)}$. Is that something that's well-known?

Apr 25 comment Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. I like this approach a lot. Thanks! Apr 25 accepted Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. Apr 25 comment Showing that $f_{2n+1}=f_{n+1}^2+f_n^2$. How did you obtain that? Did you know it beforehand?

Apr 25 accepted If $f$ is increasing and continuous on $[a,b]$, then it is integrable there. Apr 24 asked If $f$ is increasing and continuous on $[a,b]$, then it is integrable there.

I also had the same feeling about this inequality. I will comment here again when I check whether this is a typo or not. Thanks!
