线性代数示例

$A = (1, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, 18, 19)$ , $b = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)$

解题步骤 1

建立集合 ${1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}$ 和 ${1, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, 18, 19}$ 的交集符号。

${1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20} \cap {1, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, 18, 19}$

解题步骤 2

两个集合的交集是两个集合中的共同元素的集合。

${1, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, 18, 19}$

解题步骤 3

这两个集合的补集是 ${1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}$ 中不属于这两个集合的交集部分的其余元素。

${2, 4, 8, 10, 14, 16, 20}$
