Domain And Range Of Inverse Trigonometric Functions Graph

The domain of an inverse function is the range of the original function and the range of an inverse function is the domain of the original function.

Domain and range of inverse trigonometric functions graph. To make the students to understand domain and range of a trigonometric function we have given a table which clearly says the domain and range of trigonometric functions. The inverse function of f x tan x x in dfrac pi 2. Represent angles or real numbers and their sine is x cosine is x and tangent is x given that the answers are numerically smallest available. It is even function graph of sec x function cosecant function y f x cosec x domain it is defined for all real values of x except x nπ where n is any integer range.

Inverse trigonometric functions in maths trigonometry is a measurement of triangle and it is included with inverse functions. Let y f y sin x then its inverse is y sin 1 x. As we can see from the graph of the sine function many different angles. The graphs of y sin x and y sin 1 x are as given in fig 2 1 i ii iii.

1 1 period 2π it is odd function graph of cosec x function we can write the range for the trigonometric functions in below summary table also read. More clearly from the range of trigonometric functions we can get the domain of inverse trigonometric functions. The dark portion of the graph of y sin 1 x represent the principal value branch. Domain of sin x and cos x in any right angle triangle we can define the following six trigonometric ratios.

Examining the graph of tan x shown below we note that it is not a one to one function on its implied domain. Definition of arctan x functions. It also termed as arcus functions anti trigonometric functions or cyclometric functions. The inverse of g is denoted by g 1.

Domain of inverse trigonometric functions. Each operation has the opposite of its inverse. But if we limit the domain to dfrac pi 2 dfrac pi 2 blue graph below we obtain a one to one function that has an inverse which cannot be obtained algebraically. Already we know the range of sin x.

Before reading this post you may wish to review graphs of basic trigonometric functions and introduction to inverse trigonometric functions. In this post we study the graphs of inverse trigonometric functions. Because the trigonometric functions are not one to one on their natural domains inverse trigonometric functions are defined for restricted domains. It has been explained clearly below.

That is range of sin x is 1 1 and also we know the fact domain of inverse function range of the function. Sin 1 x cos 1 x tan 1 x etc.
