The following is false. Show a counterexample and prove the correct statement. If f(x) is differentiable on a, possibly infinite, interval (a,b) and if limx->b f\'(x)=infinity, then f(x) is NOT uniformly continuous on (a,b). Solution the derivative of a uniform continuous distribution should be 0. because the height of the distribution is a flat line between the bounds (a,b). the distribution of a uniform continuous variable looks like a rectangle. If the derivative of the function was infinity it would probably be an exponential distribution..
