When a group of joints have the same dip angle and a strike angle, that group is known as a joint set. Assume there are eight joints in the rock core with the following dip angles: 32, 67, 35, 65, 28, 64, 62, 30, and 31. It is clear that there are at least two joint sets.
A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets.
What is a joint set in mathematics?
Two sets are said to be joint sets when they have atleast one common element. Example: X = {1, 5, 9} Y = {2, 5, 11}
What is joint sets A and B?
A and B are joint sets. If set A and set B are non empty sets and A ∩ B is empty set then they are disjoint set. A = {1, 4, 6} and B = {2, 5, 7} A ∩ B = Φ
What are joint and disjoint sets?
What is a joint set and disjoint set? Suppose A and B are two non-empty sets such that these two sets are called joint sets if A ⋂ B is a non-empty set. If A ⋂ B is an empty set, then A and B are called disjoint sets.
What is equal set with example?
Equal sets are defined as the sets that have the same cardinality and all equal elements. In other words, two or more sets are said to be equal sets if they have the same elements and the same number of elements. For example set A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5}. Therefore, A and C are equivalent sets.
What are the different kinds of set?
Answer: There are various kinds of sets like – finite and infinite sets, equal and equivalent sets, a null set. Further, there are a subset and proper subset, power set, universal set in addition to the disjoint sets with the help of examples.
Are all equal sets joint sets?
Equal sets are always equivalent. Equivalent sets may not be equal. Disjoint Sets: Two sets A and B are said to be disjoint, if they do not have any element in common.
Are two sets A and B equal?
Definition 2: Two sets A and B are said to be equivalent if they have the same cardinality i.e. n(A) = n(B). In general, we can say, two sets are equivalent to each other if the number of elements in both the sets is equal. And it is not necessary that they have same elements, or they are a subset of each other.
What is cardinality of set?
The size of a finite set (also known as its cardinality) is measured by the number of elements it contains. Remember that counting the number of elements in a set amounts to forming a 1-1 correspondence between its elements and the numbers in {1,2,,n}.
What is a union B if A and B are disjoint set?
Two sets are said to be disjoint if they have no element in common. The number of elements in the union (A∪B) is simply the sum of the number of elements in A and the number of elements in B: |A ∪ B| = |A| + |B|.
What is equivalent set?
Equivalent sets are the sets with equal number of elements in them.
What is overlapping set?
Two sets are said to be overlapping if they contain at least one element in common. A= {1, 2, 3, 4} and B={4, 7, 1, 9} are said to be overlapping sets. Disjoint Set: Two sets are said to be disjoint, if they do not have any element in common.
What are disjoint pairs?
A kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can’t be used in both pairs). Note: Disjoint means that the two pairs are totally separate. The diagonals are perpendicular.
What makes a set equal?
Lesson at a Glance
Sets can be equal to each other or equivalent. If the sets are equal, they have the exact same elements in them. If they are equivalent, they have the same number of elements, or cardinality. Although these sets are different categories, they have the same number of elements, making them equivalent.
What is equal or equivalent?
Equal and equivalent are terms that are used frequently in mathematics. The main difference between equal and equivalent is that the term equal refers to things that are similar in all aspects, whereas the term equivalent refers to things that are similar in a particular aspect.
