Examples of Use of Intersection Distributes over Union
Let:
\(\ds A\) | \(=\) | \(\ds \set {3, -i, 4, 2 + i, 5}\) | ||||||||||||
\(\ds B\) | \(=\) | \(\ds \set {-i, 0, -1, 2 + i}\) | ||||||||||||
\(\ds C\) | \(=\) | \(\ds \set {-\sqrt 2 i, \dfrac 1 2, 3}\) |
Then:
\(\ds \paren {A \cap B} \cup \paren {A \cap C}\) | \(=\) | \(\ds \set {-i, 2 + i} \cup \set 3\) | ||||||||||||
\(\ds \) | \(=\) | \(\ds \set {3, -i, 2 + i}\) |
