relative frequency in r

Let u be the frequency of a wave. That is, the number of vibrations completed by a particle in one second is u . Time taken to complete u vibrations = 1 second. . But time taken to complete one vibration is defined as the time period of the wa..

A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty set..

If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b. Let R mean 'is greater..

To show that f = R/2 where f is the focal length of a mirror and R its radius of curvatu..

Wave velocity is defined as the distance traveled by the wave in one second. Or Wave velocity = Wavelength frequency..

Let R A x B be a relation from A to B. Then the inverse of R, denoted by R -1 is a relation from B to A, defined as Clearly, Domain of R - 1 = Range of R and Range of R -1 = Domain of R..

Consider the set A = {a, b, c, } then any subset of A x A is called a relation in A. Let R be any relation in A so that R is a subset of the product set A x A. We will discuss the properties a relation may possess.Consider the set A = {a, b, c, } th..

Reflexive property: A relation R in a set A is said to be reflexive if every element of the set A is related to itself. This is if aRa where a A, or (a, a) R for each a A. Transitive property: A relation R, is said..
