1) B = (0,1) U {2}, the derived set of B which contains all limit points in B is [0,1], right?
2) B = (0,1) intersect Q,the closure of B is [0,1] too right?
3) a subset of R whose only limit point is 1... Will {1+ 1/n: n is natural number} work?
4)
an interval on which the function f(x) = 1/(1-x^2} is uniformly continuous
R \ {1} work?
