Mathematics Relation

Equivalence relations permeate mathematics with several salient examples readily available:

1. Residue classes [a]N consist of all numbers congruent (equivalent) modulo N
2. a negative number is a set of all equivalent pairs (a,b) of integers with a3. a rational number is a set of all equivalent pairs (a,b) of integers, where two pairs (a,b) and (c,d) are equivalent iff ad = bc
4. an irrational number is an equivalence class of sequences r1, r2, r3, ... of rational numbers, where two sequences {ri} and {si} are equivalent iff they have limits as i and their limits coincide.

Love relations

It may be easy to look around our world today and see the appearance of chaos, difficulty and strife. Yet, when we come from an open heart, we can also see our opportunity to love all things into balance, joy, harmony and peace. This planet does not need more visions of desperation, fear, doubt and hate - it requires an abundance of love, especially unconditional love, to heal and restore the beauty contained in every moment. This becomes the easier path once we take the first step and begin to share our love.

When we bring unconditional love back into our personal, professional, community and family lives, we begin the journey of restoring wholeness and happiness to our planetary adventure. Of course it takes determined effort on our part as the old ways of being are quick to return in our mind. However, this effort to love is rewarded with a new perspective on everything and all life benefits as a result.

relationship between carrying cost and ordering cost

If various items in stock are multiplied by their purchasing price, one is able to determine the “A” items, those few that account for the highest value, the “B” items, those that come next and account for less value, and the “C” items, the remaining large number of items that have a far smaller share of the total value of inventory. By concentrating on the “A” items and then the “B” items one can develop a strategy that rest on reducing the quantities of “A” and “B” items held in stock to the optimum level. An important element of this strategy consist of placing several orders of smaller quantities for “A” and “B” items per year instead of placing one order for whole year and keeping these in stock. The smaller the size of the order the less are the carrying costs. But the same, if more orders are placed then an extra cost is incurred as this may entail hiring more personnel to place and process these orders, and increased paperwork.Therefore the greater number of order in smaller quantities. The lower will be the carrying costs, but the ordering costs may increase. The optimum solution would where the two curves intersect.






In developing in ordering strategy we need to take two decisions: How much to order of each item in the “A” and “B” categories or what is the economic order quantity (EOQ); and when to order this quantity or the reorder point. To determine EOQ, three figures are needed: The first two are the average inventory for the item, in monetary terms, and the ordering costs, taken as the incremental cost pear or the cost of each additional order. If an enterprise places more orders, there is an increased cost consisting mainly of the salaries of the extra staff that will be required, as well as extra stationery and supplies. The third figure that is needed is the carrying costs. Ordering costs for placing orders, expediting, inspection, and changing or setting up facilities to produce in-house.Carrying costs on invested capital, handing, storage, security, insurance, taxes, obsolescence, spoilage, and data-processing costs.

Relationship Introduction

Different languages have different terms for relationships, and even distinguish different relationships. For instance, Swedish calls your mother’s brother “morbror” and your father’s brother “farbror”, where Danish has “onkel” for both, and English has “uncle”. (In Latin they were “avunculus” and “patruus”.)
On the other hand, English makes some distinctions that other languages do not. Your daughter-in-law and your stepdaughter are both your “belle-fille” in French. And according to the Encyclopædia Britannica, Polynesian languages use the same words for male and female cousins as for brothers and sisters.
Even native English speakers can be confused by some of our relationship terms. A friend asked me to help him figure out what relation he was to his mother’s aunt’s great-grandson. After we had worked that out (see Example 2), he suggested others might be interested. What follows is an expanded and more general form of our discussion.
In English, three sets of terms seem to cause the most difficulty: cousin, in-law, and “half” or “step” relations. Just to make things messy, each of these terms can correctly be used for several different relationships.
Vocabulary: In discussing relationships, phrases like “brother or sister” and “son or daughter” come up again and again. Here are standard gender-neutral terms that I’ll use to shorten the following discussion:
sibling = brother or sister (Some dictionaries call two individuals siblings if they have one or both parents in common. This would include the relationships of half brother and half sister as well as full brother and sister. In this document, I’ll use the word “sibling” in its more restricted meaning: an individual who has the same two parents as you.)
spouse = husband or wife
child = son or daughter (even if an adult)
parent = mother or father

Mother Daughter Relationship

Mother Daughter Relationship:

"I still hear you humming, Mama. The color of your song calls me home. The color of your words saying "Let her be. She got a right to be different. She gonna stumble on herself one of these days. Just let the child be." And I be, Mama."The closest bond in the family is the one that is shared by a mother and her daughter. Theirs is a bittersweet relationship, which goes through numerous ups and downs in life and in the end, still turns out to be the most intimate of all the other relations. In her childhood, a daughter copies her mom and wants to be just like her. At the age of five, her mother is like her goddess. She smears her face with her mom's lipstick and models her earrings and high heels, wanting to be just like mommy. She applies her nail polish, mimics her creams-smothering motion and tries to do every thing that she sees her mother doing.

Relationship between parents and children is very important and particulary their relation with their mothers

Relationship between parents and children:

Relationship between parents and children is very important particulary with their mothers. Yet, some mothers don’t care about their children and don’t pay attention to them. The cause of this problem is the mothers working. First, children need their mother’s affection. Second, they want to have a mother who helps them in their studies and in their own life. Unfortunately, they are deprived of this right, for, the mother works all the day outside and at home. At night she ends up tired and she sleeps quickly. Children want more time to enjoy their childhood ; if they don’t, they will be affected by bad friends and learn dangerous habits such as smoking, drinking, drugs which may lead them to delinquency and consequently the children will fail in their school life. Finally, children need their mother with them all the day to make them feel self confident... How nice is to have a non-working mum ! It’s a great pity to have a working one. Don’t you think so?

Personality and Relationships

Most of us are probably allured by the attractive notion that effortless relationships exist. Whether it be happily-ever-after marriages, or friendships which last forever, or parent/child bonds which supercede the need to understand each other, we'd all like to believe that our most intimate relationships are unconditional, and strong enough to withstand whatever may come. However, at some point in our lives most of us need to face the fact that relationships require effort to keep them strong and positive, and that even wonderful, strong relationships can be destroyed by neglect.

Mother Son Relationship.

Mother Son Relationship.
A mother has undying love for her children. Her presence itself deeply affects the entire life of her little one. Our mother is the first woman in our life and cannot be replaced by anyone. Though a mother loves all her children equally, despite distinction of sex, it has been seen often that a daughter is always more attached to her father, while a son is closer to his mother. A mother's love always makes her son stronger as well as balanced in his life. While a father makes his son strong enough to fight with the world, it is the mother who teaches him when and where to think from his heart.

relation


Relation:


In mathematics, a binary relation on a set A is a collection of ordered pairs of elements of A. In other words, it is a subset of the Cartesian product A2 = A × A. More generally, a binary relation between two sets A and B is a subset of A × B. The terms dyadic relation and 2-place relation are synonyms for binary relations.
An example is the "divides" relation between the set of prime numbers P and the set of integers Z, in which every prime p is associated with every integer z that is a multiple of p (and not with any integer which is not a multiple of p). In this relation, for instance, the prime 2 is associated with numbers that include −4, 0, 6, 10, but not 1 or 9; and the prime 3 is associated with numbers that include 0, 6, and 9, but not 4 or 13.
