Lecture , Tuesday 1999/11/30, 8:00-9:50 AM: Showed by \epsilon - \delta that f(x) = sqrt( abs(x) ) is uniformly continuous. Also quote the theorem on compact sets for a short proof Gave well known examples of discont functions. (1) f(x) = 0 on irrationals, 1 otherwise. (2) f(x) = 0 on rationals, 1/p on x = q/p. seperate continuous and jointly continuous. 1-d calculus, eg: cont, but not diffrentiable at 0 differentiable but not continuously diff at 0.
