Riemann integral proofs.

  1. Jun 19, 2011 #1
    1. The problem statement, all variables and given/known data
    Prove or falsify the statement (see picture)


    3. The attempt at a solution
    I've got the answer already but I want to make sure I know is what is meant by f(x)>g(x) for x in [a,b]. Does it mean f(x) lies above g(x) throughout the entire interval?

    Yes fix)> g(x) means that, for every value of x in the interval, f(x) is larger that g(x).
