- As others have pointed out, this is impossible. Fortunately, the error has
- been corrected in Gelbaum's newer book _Problems in Real and Complex Analysis_,
- (Springer, 1992).
-
- Here, the problem (2.10) is stated as follows:
-
- 2.10 True or false: R is the continuous image of [0,1)?
-
- In the solution, the map f(x) = [1/(1-x)] sin [1/(1-x)] is used.
