An intersection in precalculus refers to the set of common elements between two or more sets. In other words, it is the overlap between the sets. On the other hand, a union in precalculus refers to the combination of all elements from two or more sets. It includes all elements, even if they are repeated in different sets.
The symbol for intersection in precalculus is ∩ and the symbol for union is ∪.
To find the intersection of two sets, you need to compare the elements in the two sets and identify the common elements. To find the union of two sets, you need to combine all the elements from both sets, including any repeated elements.
A universal set in precalculus is the set of all possible elements that can be included in a given context. It is denoted by the symbol U. A null set, on the other hand, is a set that does not contain any elements. It is denoted by the symbol ∅.
A set A is considered a subset of another set B if all the elements in set A are also present in set B. In other words, every element in set A can also be found in set B. This can be represented mathematically as A ⊆ B.
