WebTwo sets are equal if they have the same elements. 🔗. A set A is a subset of a set B if every member of A is also a member of B. For example, suppose C = {Al, Bob, Chris, David, Ed} and A = {Bob, David}. Then A is a subset of C, written as A ⊆ C. 🔗. Notes: Every set is a subset of itself, A ⊆ A. WebJun 25, 2024 · This same set can be written in set notation: {x ∈ R ∣ x < 5 or 10 < x < 20 or x > 100} Finally, note that if the characterization of the set is rather complex, the set notation becomes preferable to the interval one, which would require a great number of intervals in the union. In some other cases, it could be literally impossible to write ...

The original family of intervals produces an intersection of {0}, as the element 0 is in every set of the form (-1/k, 1/k), but for every real number r > 0, there is a k such that 1/k < r, so r is not contained in the interval (-1/k, 1/k), and a similar argument holds for r < 0. (a, b) is the set of all reals x such that a < x < b. WebUse interval notation to describe sets of numbers as intersections and unions.
