how big is your 'n'?

did you know that there is quite a difference between 2n/2n+1 and 3n-1/3n?
just came by to tell you that i couldn't believe, even if i knew that 3n-1/3n is smaller. it's not very visible when playing with small n. modesty isn't very much appreciated. so i tried with a million, and mathcad 7.0 professional. and it worked. and i'm a happy student again. ... unfortunately, i have to study now (so much of a happy student).
