Set infinite set co., Ltd. Set. The set is available and the relative universe. Set (Sets) refers to a group of things, whether they are people or animals, which are mathematical expressions can identify members of the group, and called on "members of". Writing set Writing set used caps instead of writing the name of a writable and set 2. 1. the distribution of members. For example, A = {1, 2, 3, 4, 5}. B = { a, e, i, o, u} C = {...,-2,-1,0,1,2,...} 2. tell the condition of the members of the set. For example, A = {x | x is a positive integer that is less than or equal to 5} B = {x | x is in English.} C = {x | x is an integer}. The set of symbols that represents a number of options: I-set of integers instead of deleting the set of Q-rational agent that is deleted. Instead, I + Q + set of positive integers instead of a set of positive rational number. I represent the set of integer and rational number Q instead of set. Instead, the set of N R instead of a set of cardinality. Set co., Ltd. The provisions defining the set limits are set can specify the number of elements in the set. For example, A = {1, 2, 3, 4, 5} with 5 members. B = {a, e, i, o, u} with 5 members. Infinite set Infinite set is a set that is not a set limit or set with countless number of many members. For example, เช่่น C = {...,-2,-1, 0, 1, 2, ...}. Set. Set A and set B is set equal to all the members of set A is a member of the set B, and B is the set of all members in all the members of A set can be written with the symbol A = B. For example, เช่่น A = {1, 2, 3, 4, 5}. B = {x | x is the count is less than or equal to 5} ∴ A = B Set empty. An empty set is a set with no members or the number of members in the set to zero. The symbol can be written instead by {} or Ø. For example, เช่่น A = {x | x is an integer and x 2 < < 1} A = Ø ∴. B = {x | x is a positive integer and x + 1 = 0}, B = Ø ∴ back. Because we can tell how many members of the empty set is empty, the set is a set limit. The relative universe The universe is the set that contains the Member relative to all of the things that we need to learn to write with symbols, u. For example, เช่่น If we would learn about integers. U = {...,-2,-1, 0, 1, 2, ...}, or U = {x | x is an integer.} Chop and set power set Hack set A set definition provisions as set of choppers, B if every Member of A set is a member of the set B, and can be written with the symbol A ⊂ B. Example 1 A = {1, 2, 3}. B = { 1, 2, 3, 4, 5} ∴ A ⊂ B Chop chop is A real set set set of set B ⊂ B if A ≠ B and A. The number of hack set If A is a set with n members and members. A number of the set of choppers will be set and the 2n is true set the set 2n-1 hack. Power set Chapter definition of A power set is a set that contains members that are all set of choppers and can write A replacement by P (A) symbols. Example 1 A = Ø Chop all of A set is Ø. ∴ P(A) = {Ø }Instead, illustration, writing set Intersection and difference asphalt component segments. • Writing instead photos set plans. In the diagram represent the set We are drawing close the rectangle instead of a relative universe and closing ellipse or circle instead of a set of choppers universe relative: We call this the above diagram, "Venn diagram-Euler" (Venn-Euler Diagram). • Union (Union) A Union with the set definition provisions set B is the set that contains the members that belong to A set or set B or both A and B can be written A ∪ B instead. For example, A = {1, 2, 3}. B= {3,4,5} ∴ A ∪ B = {1,2,3,4,5} • Intersection (Intersection). Article defining the intersection set A set B is the set that contains the members that belong to a set A and set B can be written instead of the symbol, A ∩ B. For example, A = {1, 2, 3}. B= {3,4,5} ∴ A ∩ B = {3} • Asphalt component segment (Complements) Chapter definitions. If A set has been compiled in the universe relative to share a segment of U set A is the set that contains the members that belong to U, but not as a member of A burn, rather than by A ' symbol. For example, U = {1, 2, 3, 4, 5}. A ={1,2,3} ∴ A' = {4,5} • The variance (the Difference). Chapter definitions. If the set A and any set B, is in the same relative universe u. The difference of A and B is the set that contains the members that belong to A set, but not a member of set B can be written with the symbol A-B. For example, A = {1, 2, 3}. B= {3,4,5} ∴ A - B = {1,2} A limited number of set members. • If A set limit can be written instead of A set with n members (A)• If A and B are the limits set in the universe relative U. n(A ∪) = n(A) + n(B) - n(A ∩ B) n(A - B) = n(A) - n(A ∩ B) n(B - A) = n(B) - n(A ∩ B)• If A, B, and C is the limit set in the universe relative U. n(A ∪ B ∪ C ) = n(A) + n(B) + n(C) - n(A ∩ B) - n(A ∩ C) - n(B ∩ C) + n(A ∩ B ∩C)
