think about it you are smart
well-defined sets are sets that can identify easily while not well-defined are those that cannot determined easily :)
set is a collection of well-defined object.
A collected of well defined objects is called a set.
A set is a collection of well-defined and distinct objects.
The description of a well defined set clealy states what is in the set. For example, "deciduous trees" is a set that only includes trees that are deciduous. No conifers or non-deciduous trees are in the set. "Tall trees" is not well defined because the members of the set depends on what "tall" means to different people. Well-defined sets can be illustrated by using pictures of what would be inside and outside a circle to show which would and would not be in the set.
A set is a collection of well defined and distinct objects, considered as an object in its own right.
Well, a rectangle is defined as having two sets of parallel sides and four right angles, a parallelogram is defined as having two sets of parallel sides and two sets of supplementary angles. Therefor, a rectangle is always, by definition, a parallelogram. A parallelogram is not always a rectangle, but it can be.
well defined
Not really, since there are several such sets. It really depends what characters you choose to include. In computers, there is the set of ASCII characters, several extended ASCII sets, the Unicode set, and several others.
A relation between two sets is defined to be any subset of the two set's Cartesian product. See related links for more information and an example.
Elements that have to be defined by personal judgement. Such as the set ofgreat songs is not well-defined. But the set of the English alphabet is well-defined.
