# Roster method to write a set of ordered

The celebrated train of was numbered M and was a yellow-and-brown lightweight passenger train, articulated and streamlined as a four-car trainset powered by a horsepower oil-distillate internal combustion engine.

Union, intersection, complement, difference. Partially, linearly and well ordered sets. Any collection of objects. No restriction is placed on the nature of the objects in a set.

They can be anything: Thus the mathematical meaning of the word set is the same as the regular, nontechnical meaning of the word.

Collection, class, aggregate, ensemble Methods of defining sets. A set can be defined in either of two ways: The first method is called the roster method and the second method is called the property method. Sets are usually denoted by capital letters such as A, B, X, S, etc. When the roster method is used to define a set, the elements of the set are usually enclosed in braces and separated by commas e.

Some authors use the colon: Sets consisting of the same elements. Two sets A and B are said to be equal if every element of A is an element of B and every element of B is an element of A.

Let S be a given set. Any set A, each of whose elements is also an element of S, is said to be contained in S and called a subset of S.

Reviewing the definition we note that the entire set S qualifies as a subset of S. Thus any set is a subset of itself. In the above example sets A, B and C are all proper subsets of S. However illogical it may seem, it is convenient and useful to have the concept of an empty set, a set containing no elements.

Often a discussion involves subsets of some particular set called the universe of discourse or briefly universeuniversal set or space. The elements of a space are often called the points of the space.

We denote the universal set by U. The set of all even integers could be considered a subset of a universal set consisting of all the integers.

Or they could be considered a subset of a universal set consisting of all the rational numbers. Or of all the real numbers. Often the universal set may not be explicitly stated and it may be unclear as to just what it is.

At other times it will be clear. Complement of a set. The complement of a set A with respect to a given universal set U is the set of elements in U that are not in A. Finite and infinite sets.

A finite set is a set with a finite number of elements and an infinite set is one with an infinite number of elements. Two sets A and B are said to be not comparable if A A We thus note that if two sets A and B are not comparable there is necessarily an element in A that is not in B and an element in B that is not in A.

Two sets are called disjoint if they have no elements in common i. A system of more than two sets is pairwise disjoint sometimes called simply disjoint if every pair of sets in the system is disjoint.

Sometimes the members of a set are sets themselves. A family of lines in geometry can be regarded as a set of sets since lines can be regarded as sets of points.

Stereograph Viewing. When I was a kid, my dad who was a physician showed me one fascinating way to view stereographic images [a pair of pictures that simulate the distance between your two eyes].].

The examples we used were three-dimensional depictions of molecules, but it works with any stereo image.

Adolf Hitler was obsessed with the occult, in his case the Thule Society, closely inter-connected with German Theosophists.

The jolly roger, skull and cross bones, "der Totenkopf" was an emblem worn by Hitler's SS soldiers and was emblazoned on SS armoured cars and tanks (see images on this page).

In set builder form, also called Rule method, we write it as A = {x/x is a prime number less than 10} expanded as “A is a set of elements x, such that x .
