Why you need for relation and function?

I'll attempt to answer this. As worded your question makes no sense. All functions are relations, but not all relations are functions. Like all girls are people but not all people are girls.


Why is the range the output and the domain the input?

A function may be defined over only certain values. That is, it may have only a certain set of values that can serve as input. For example, in elementary mathematics, the principal square root is only defined for non-negative real numbers. This is the "area" over which the function is valid and so it is called the domain. The mathematical term for the set of output values is actually the co-domain, but many people refer to it as the range.

What is a one-to-one relation in mathematics?

A one-to-one relation in math means that for every value in the range, there's at most one value that maps to it. If you think of relations as people sitting on a bus, this means that no one is sharing a seat. More often, mathematicians talk about one-to-one functions (formally called injections) - these are just one-to-one relations that happen to be functions :-). If we write the function as y=f(x), the condition for it being one-to-one is that if f(a)=f(b), then a=b. When looking at the graph of a relation, we can determine if it's one-to-one by the horizontal line test: if any horizontal line drawn on the graph intersects the relation at most once, it is one-to-one. On the other hand, if a horizontal line intersects the relation twice, the relation is not one-to-one. For example, y=x^2 is not a one-to-one relation: (-1)^2 and 1^2 both get mapped to 1. We can see this in the graph of y=x^2 because a horizontal line above the x-axis will intersect the graph twice. y=x^3, on the other hand, is a one-to-one relation. Because the cube of a negative number stays negative, no two numbers get sent to the same number by cubing them.

Application of integral calculus on food?

There is an HUGE number of applications but I'll give you an example: Say you have a function of food consumption (independent variable) against number of people. If you integrate this function you will get a figure for total food consumption.


What is meant by harmonic distortion in amplifiers?

Harmonic distortion is most simply characterised by an output which is not proportional to the input, but can be derived from the input by some function or other.Outputs which bear no relation to the input are instanced by noise, hum, motor-boating, or crackles, and are not harmonic distortion.Distorted outputs which are related to the input are in practice mostly due to a non-linearity in one or more stages, an overdrive condition, or an unbalanced phase splitting process before a push-pull output stage.Note. people have spent their whole lives on this, and books have been written. If you need to know more . . . . .

What is the function and the limit?

A lot of people think of a function as an "equation," but it can be more general than that. In formal definitions, a function is a "rule" that assigns every input to exactly one output. You might see a function as a graph, an equation, a table, or an obnoxious person that shouts back at you every word you say, but in pig latin. The limit of a function exists if, as the input x approaches something, the output f(x) approaches something--regardless of the output when x actually reaches the thing it approaches. The limit is the thing that f(x) approaches. For example, picture (or Google), the graph of f(x) = 1/x. As x approaches infinity (further and further to the right of the graph), the curve f(x) gets closer and closer to the x-axis--meaning it gets closer and closer to zero.

What is a relation in access?

Technically speaking in the terminology of databases, a relation is a table. We also talk about connecting tables to each other by establishing a relationship. Some times people use relation when talking about a relationship, but technically a relation refers to a table, which can then be involved in a relationship.Technically speaking in the terminology of databases, a relation is a table.
