comment Parabolic arclength
Awesome, thanks! I was just making up a problem for myself, so I'm glad it wasn't a mistake that lead to an algebraicly unsolvable answer. Out of curiosity, can you explain to me why it's not a function of a? I'm shocked that the ratio between a parabolas arc length between zeroes and the distance between its zeroes is simply a function of b.

comment Is there a standard classification for an Almost Integer in base 10?
I understand. I feel they should be ranked by classes, where a class N almost integer has N 9s or 0s after the decimal point. Therefor, as Lucian's comment suggests, $2\pi + e$ would be a class two almost integer, and it's square root would be class 3.

comment Converting Fibonacci number $F_{5n+3}$ to Lucas numbers $L_{n+k}$
I've actually already done that, I'm just trying to follow up with an algebraic proof.

comment Converting Fibonacci number $F_{5n+3}$ to Lucas numbers $L_{n+k}$
F_n mod 10 has a period of 60, and L_n mod 10 has a period of 12, but how does that help me?

comment Lucas Number Equivalent of the Pisano Period?
Can you show me that Lucas-to-Fibonacci conversion that includes that division by 5 and proves that $\lambda(m)|\pi(m)$ bit?

What do you mean $(m,5) = 1$?

comment Lucas Number Equivalent of the Pisano Period?
Haha, if that's true, then you'd be saving me more work, not derailing my current work. Unfortunately, it's not true. $\pi(10) = 60$ while $\lambda(10) = 12$.
