BM6. Set Operations

Показать описание
Basic Methods: We introduce the basic set operations of union, intersection, and complement, which mirror the logical constructions of or, and, and not. We note the main laws for these set operations and give more examples of double inclusion proofs. Finally we consider indexed families of sets and logical quantifiers.

You can absolutely use strings of tautologies, but away from logic it doesn't happen often. Typically one direction is easy and the other is difficult.

For that second line, you need to include "or(x not in A and x not in B)". Hope it worked out.

You're welcome, and thanks for the kind words! I do feel that I lose a lot going to video. The classroom has its own energy.

Hi MathDoctorBob, I know that this video us old but I found this very helpful.  In my computer science class our prof gave us examples to simplify using the basic set identities.  Do you have any videos that have examples like  (AUC) n ((AnB) U (C'nB))=AnB.  I used n for the intersection sign. Thanks so much!
