# Equivalence

## What is equivalence and example?

The definition of equivalent is something that is essentially the same or equal to something else. An example of equivalent is (2+2) and the number 4. Since 2+2= 4, these two things are equivalent.

## What is the concept of equivalence?

## Is equivalence a real word?

The noun equivalence describes the state of being equal, and it can be used any time things are basically interchangeable. If you came down with a stomach bug and there were three different medicines your doctor could prescribe — any one of them being likely to cure you — they would have an equivalence.

## What does equivalent mean in math?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). Examples.

## What is the meaning of moral equivalence?

Moral equivalence is a term used in political debate, usually to deny that a moral comparison can be made of two sides in a conflict, or in the actions or tactics of two sides. The term had some currency in polemic debates about the Cold War, and currently the Arab–Israeli conflict.

## What is equivalence in chemistry?

An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction.

## What is equivalence theory law?

THE GENERAL THEORY. Presentation and summary. Two states are “individualistically equivalent,” or, for short, “equivalent,” when all individuals are indifferent between them (unanimous indifference). The “principle of equivalence” consists of considering properties in states equivalent in this sense to the actual one.

## What is equivalence relation in maths?

An equivalence relation is a relationship on a set, generally denoted by “∼”, that is reflexive, symmetric, and transitive for everything in the set. 1. (Reflexivity) a ∼ a, 2. (Symmetry) if a ∼ b then b ∼ a, 3. (Transitivity) if a ∼ b and b ∼ c then a ∼ c.

## What does “equivalence” mean?

equivalence – a state of being essentially equal or equivalent; equally balanced; “on a par with the best”. equality, equation, par.

## What does “equal” mean in math?

1. the state or fact of being equivalent; equality in value, force, significance, etc. 2. an instance of this; an equivalent. 3. the state of having equal chemical valence. 4. Logic. a. the relation between two propositions such that they are either both true or both false.

## What is the meaning of equality?

The state or condition of being equivalent; equality. 2. Mathematics An equivalence relation. 3. Logic The relationship that holds for two propositions that are either both true or both false, so that the affirmation of one and the denial of the other results in contradiction.

## What is logical equivalence?

Logical equivalence, where two statements are logically equivalent if they have the same logical content

## What is equivalent class?

Equivalence class (music) Equivalent VIII, or The Bricks, a minimalist sculpture by Carl Andre. Equivalents, a series of photographs of clouds by Alfred Stieglitz.

## What is equivalent lens?

Equivalence, at its most simple, is a way of comparing different formats (sensor sizes) on a common basis. This is already the way most lenses are talked about: it’s quite common to say that a compact camera includes a ’28-120mm lens’ but the key and (often unspoken) word in that description is ‘equivalent.’ It’s a simple way of describing the range of fields-of-view that the lens offers, cancelling out the effect of sensor size by using a common reference point.

## How much FOV does APS-C have?

It’s easy enough to say that APS-C is a 1.6x crop and that you get effectively 60% of the FOV of a FF sensor. It’s also fair to say that the DoF will be affected by a similar percentage, resulting in a (60%?) larger circle-of-confusion by the smaller sensor for a given f-stop.

## Why is the entire article written without reference to pixel size?

The entire article is intentionally written without reference to pixel size, to avoid reinforcing the widely-held misconception about the importance of pixel size. If the larger sensor has the same number of pixels, then its image is cleaner. The light per unit area is the same and each pixel has a larger area.

## Is equivalence *1 a controversial concept?

The concept of ‘equivalence *1 ‘ is still somewhat controversial and not always clearly understood. We thought it was about time we explained – and demonstrated – what equivalence means and what it doesn’t.

## What is an equivalence relation?

In mathematics, an equivalence relation is a binary relation that is reflexive, symmetric and transitive. The relation “is equal to” is the canonical example of an equivalence relation. Each equivalence relation provides a partition of the underlying set into disjoint equivalence classes. Two elements of the given set are equivalent to each other, …

## What is the relationship between equivalence and order?

Just as order relations are grounded in ordered sets , sets closed under pairwise supremum and infimum, equivalence relations are grounded in partitioned sets , which are sets closed under bijections that preserve partition structure. Since all such bijections map an equivalence class onto itself, such bijections are also known as permutations. Hence permutation groups (also known as transformation groups) and the related notion of orbit shed light on the mathematical structure of equivalence relations.

## What does the row and column indices of nonwhite cells mean?

The row and column indices of nonwhite cells are the related elements , while the different colors, other than light gray, indicate the equivalence classes (each light gray cell is its own equivalence class). In mathematics, an equivalence relation is a binary relation that is reflexive, symmetric and transitive.

## What is the relation between natural numbers greater than 1?

The relation “has a common factor greater than 1 with” between natural numbers greater than 1, is reflexive and symmetric, but not transitive. For example, the natural numbers 2 and 6 have a common factor greater than 1, and 6 and 3 have a common factor greater than 1, but 2 and 3 do not have a common factor greater than 1.

## Which two natural numbers have a common factor greater than 1?

For example, the natural numbers 2 and 6 have a common factor greater than 1, and 6 and 3 have a common factor greater than 1, but 2 and 3 do not have a common factor greater than 1. The empty relation R (defined so that aRb is never true) on a non-empty set X is vacuously symmetric and transitive, but not reflexive.

## Is equality a partial or equivalence?

Equality is both an equivalence relation and a partial order. Equality is also the only relation on a set that is reflexive, symmetric and antisymmetric. In algebraic expressions, equal variables may be substituted for one another, a facility that is not available for equivalence related variables.

## Can a relation be proved independent of each other?

An implication of model theory is that the properties defining a relation can be proved independent of each other (and hence necessary parts of the definition) if and only if, for each property, examples can be found of relations not satisfying the given property while satisfying all the other properties. Hence the three defining properties of equivalence relations can be proved mutually independent by the following three examples:

## What is the difference between equivalence and equivalent?

is that equivalent is anything that is virtually equal to something else, or has the same value, force, etc while equivalence is (uncountable) the condition of being equivalent or essentially equal.

## What does “equivalence” mean?

is that equivalent is to make equivalent to; to equal while equivalence is to be equivalent or equal to; to counterbalance.

## When are finite sets equal?

Finite sets A and B are equivalent sets only when n” (A) = ”n” (B) ”i.e. , the number of elements in A and B are equal.

## Do equivalent sets have the same number of elements?

Equivalent’ sets should , by rights, have the same “number” of elements. For this reason we sometimes say that ”’equivalent sets have the same ”cardinality .
