using therom 6-4 is the Riemann condition for
integrability. U(f,P)-L(f,P)< ε , show f is Riemann
integrable (picture included)
2. (a) Let f : 1,5] → R defined by 2 if r73 f(3) = 4 if c=3 Use Theorem 6-4 to show that f is Riemann integrable on (1,5). Find si f(x) dx. (b) Give an example of a function which is not Riemann intgration
