Question

define complement of a set with example​

Answer 1

Answer:

Complement of a Set. Let's say that we have a set A that is a subset of some universal set U. The complement of A is the set of elements of the universal set that are not elements of A. In our example above, the complement of {-2, -1, 0, 1} is the set containing all the integers that do not satisfy the inequality.

Answer 2

0. it is actually quite simple ..A set in topological space X or a maximal connected set in x if a is connected is not a subset of any other connected set in x therefore if A is a component and B connected set ACB then is A=B
