If it does, what is the limit function? Does the sequence * converge uniformly on **? Does it converge uniformly on [0,1]? OK I've found that the sequence does indeed converge pointwise to f(x) = 1, and that it does not converge uniformly on **. I am however, struggling to work out if it converges uniformly on [0,1], Any help is appreciated, Thank you.
