Section 36*: Problem 2 Solution
Working problems is a crucial part of learning mathematics. No one can learn topology merely by poring over the definitions, theorems, and examples that are worked out in the text. One must work part of it out for oneself. To provide that opportunity is the purpose of the exercises.

The space is compact and Hausdorff, therefore, normal. Cover it with a finite number of open sets
such that each can be imbedded into
, let
be the corresponding collection of imbeddings. By Theorem 36.1, there is a partition of unity
dominated by
. Similar to the proof of Theorem 36.2, we construct
so that it is continuous and injective.
