Ruler function proof
Not what you're looking for?
Define Ruler Function g:(0,1)-> R (it is the usual ruler function available online)
as g(x) = { 1/q if x = p/q, p and q are relatively prime
{ 0 if x is irrational.
Show (without using Riemann-Lebesgue Theorem) that g is Riemann integrable.
The hint says that since L (lower sum) is zero, it remains to show that U (Upper sum) is less than epsilon for some partition p. I'm trying to do that, but to me the answer is elusive.
