Re: SO You think you are smart??Man Solve this =(

According to what I've got here;
if n = 144
t = 9.999999999999995

And if n = 145, then t > 10.


Boy let me tell you what:
I bet you didn't know it, but I'm a fiddle player too.
And if you'd care to take a dare, I'll make a bet with you.

Rounding errors, presumably.
In any case, analytic answers are better than computed ones, where they're possible.


Why did the vector cross the road?
It wanted to be normal.
