This post we will see given a function, how to check if it is one-one function or not. Lets first start with the definition of the one-one functions Definition of one-one functions A function f: A-> B is said to be one-one if, and only if, for all elements a1 and a2 in A, if […]

For a functionf:A ->B Set A is called the domain of the function fSet B is called the co-domain of the functionThe set of Images of all elements in Set A is called the range i.e it is the set of values of f(x) that we get for each and every x in the domain

Here is the Relation and function class 12 formulas What is Relations A relation R from a non-empty set A to a non-empty set B is a subset of the Cartesian product A × B. It “maps” elements of one set to another set. The subset is derived by describing a relationship between the first

Into functions are those functions where range is a subset of the codomain of the functions but range is not equal to co-domain Definition A function f: A-> B is said to be into if every element of B is not image of some element of A under f, i,efor every y ? B, there

Here in this post , we will see how to find the inverse of a function Inverse Function How to find the inverse of a function Method I Method II Method III Let f(x) be the function and $f^{-1}(x) $ be the inverse We can use below equation $f(f^{-1}(x)) =x$ Example f(x)=4x -2 $f(f^{-1}(x)) =x$or$4

Inverse trigonometric functions are the inverse functions of the basic trigonometric functions: sine, cosine, and tangent. To define these inverse functions, we need to restrict the domain and range of the original functions so that they become one-to-one and onto. Here are the domain and range for each of the primary inverse trigonometric functions: Domain:

In this article, we will look at standard identities as well as some other Algebraic identities. In addition, we will attempt to derive these identities without using the binomial theorem. We’ll also look at some solved examples of problems that use these mathematical identities to solve them. What is an Algebraic Identity An Algebraic identity

We will be checking how to find the values of Sin 18, cos 18, tan 18, sin 36,cos 36 degrees with the normal known values of the trigonometric ratios i.e with out the use the calculator Value of sin 18 degrees Let   $A = 18$ Now, we need to convert into known common values,so $5A
