With you coming up with 25 years as well, I think it does!  |
Cool
. Then I don't have to recheck it then..
I did the derivative of that thing on the fly, so hopefully there isn't a mistake there!
btw, that k/(1-k) formula I used to derive the second one is just the sum of a geometric series - which is very easy to prove.
