There are nine such pairs in the Cartesian product since three elements are there in each of the defined sets A and B. The Cartesian product of two sets A and B, denoted AB, is the set of all ordered pairs (a, b) where a is in A and b is in B.In terms of set-builder notation, that is = {(,) }. For example, if ], \(\left(\text{a}, 1\right), \left(\text{a}, 2\right), \left(\text{a}, 3\right), \left(\text{b}, 1\right), \left(\text{b}, 2\right), \left(\text{b}, 3\right), \left(\text{c}, 1\right), \left(\text{c}, 2\right), \left(\text{c}, 3\right)\), \begin{equation*} ) This example shows how to calculate the Cartesian product of several vectors using the expand.grid function.

The last checkbox "Include Empty Elements" can be very helpful in situations when the set contains empty elements. 3 \newcommand{\Tg}{\mathtt{g}} Find all differences between two or more sets. \newcommand{\Tr}{\mathtt{r}} } {2, Let \(A\) and \(B\) be finite sets. {\displaystyle \{X_{i}\}_{i\in I}} The cardinality type would be one-to-many, as the ProductID column in the Product table contains unique values. If a tuple is defined as a function on {1, 2, , n} that takes its value at i to be the ith element of the tuple, then the Cartesian product X1Xn is the set of functions. x (1.) In mathematics, the power set is defined as the set of all subsets including the null set and the original set itself.
