WebSelf-determination theory (SDT) is a well-established theory of motivation that posits that we grow optimally to the degree to which we are afforded "autonomy support", the collective term for the provision of opportunities to satisfy our needs for autonomy, relatedness, and competence.

WebSep 5, 2024 · Theorem 1.1.1 Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B. The set θ = {x: x ≠ x} is called the empty set. This set clearly has no elements. Using Theorem 1.1.1, it is easy to show that all sets with no elements are equal.

If o is a member (or element) of A, the notation o ∈ A is … See more A set is pure if all of its members are sets, all members of its members are sets, and so on. For example, the set containing only the empty set is a … See more Many mathematical concepts can be defined precisely using only set theoretic concepts.

For example, the number 120 has the prime factorization = which gives the multiset {2, 2, 2, 3, 5}. A related example is the multiset of solutions of an algebraic equation. A quadratic equation, for example, has two solutions. However, in some cases they are both the same number.
