Uniform convergence

  1. Dec 3, 2007 #1
    1. The problem statement, all variables and given/known data
    Suppose:
    fn goes to f pointwise on [a,b]
    For each c in (a,b) fn goes to f uniformly on (c,b), and for some M, fn(x) is less than M for all n, all x in [a,b]
    Prove fn goes to f uniformly on [a,b]

    2. Relevant equations



    3. The attempt at a solution
    I think I proved that we can choose c sufficiently close to a such that fn converges to f uniformly on (a,b). I can't see how to show that fn converges uniformly when we include the endpoints. Is more information necessary? If so, what do we need to know?
