## What are the domain restrictions for sin Cos Tan?

Graphs of Inverse Trigonometric Functions

Function Domain Range
sin−1(x) [−1,1] [−π2,π2]
cos−1(x) [−1,1] [0,π]
tan−1(x) (−∞,∞) (−π2,π2)
cot−1(x) (−∞,∞) (0,π)

## What is the domain of sin?

all real numbers
The graph of the sine function looks like this: Note that the domain of the function y=sin(x) ) is all real numbers (sine is defined for any angle measure), the range is −1≤y≤1 .

What is a restricted domain?

The use of a domain for a function that is smaller than the function’s domain of definition. Note: Restricted domains are commonly used to specify a one-to-one section of a function.

### How do you find the domain of a trig function?

The domain and range of trigonometric functions are the input values and the output values of trigonometric functions, respectively.

1. For sin θ, Domain = (-∞, + ∞), Range = [-1, 1]
2. For cos θ, Domain = (-∞, + ∞), Range = [-1, 1]
3. For tan θ, Domain = R – (2n + 1)π/2, Range = (-∞, +∞)

### How do you write a function with a restricted domain?

How To: Given a function written in equation form, find the domain.

1. Identify the input values.
2. Identify any restrictions on the input and exclude those values from the domain.
3. Write the domain in interval form, if possible.

What is a naturally restricted domain?

Natural domain is basically the x values for which the function is defined (not defined by the question, but defined by the function itself). ‘Domain’ or ‘restricted domain’ is ‘man-made’ you could say. It’s placed by the question, or by a previous part to the question which established a restriction.

#### How to restrict the domain of a sine function?

How to restrict a domain: Restrict the domain of the sine function, y = sin x, so that it is one to one, and not infinite by setting an interval [-π/2, π/2] The restricted sine function passes the horizontal line test, therefore it is one to one Each range value (-1 to 1) is within the limited domain (-π/2, π/2).

#### What is the domain of sin -1(x)?

Domain of inverse function = Range of the function. So, domain of sin -1(x) is. [-1, 1] or -1 ≤ x ≤ 1. In the above table, the range of all trigonometric functions are given. From the fact, “Domain of inverse function = Range of the function”, we can get the domain of all inverse trigonometric functions.

Are there any restrictions on the domain and range of functions?

There may be restrictions on the domain and range. The restrictions partly depend on the type of function. In this topic, all functions will be restricted to real number values. That is, only real numbers can be used in the domain, and only real numbers can be in the range.

## What does it mean when a problem has a restricted domain?

A restricted domain means that we are limiting the possible values that our variable can be. If your problem has a restricted domain, it will show it right next to the problem. When we have a problem with a restricted domain, it means that we need to find solutions that are within the restricted domain.
