Tamo . Suppose that a sequence of functions fn converges pointwise to a function f on a set E, but there exists a sequence of points In E E such that \fn(2n) – f(2n) > for some strictly positive l. Then fn does not converge uniformly to f on E. (You don't need to prove this here, but it should be clear why this is true.) Now let nar2 fn(L) = 2 +n323 Show that fn converges pointwise on [0,0]...
