# What is the domain of the cosine function?

## What is the domain of the cosine function?

The domain of the function y=cos(x) is all real numbers (cosine is defined for any angle measure), the range is −1≤y≤1 .

What is one period of a cosine function?

The period of a periodic function is the interval of x-values on which the cycle of the graph that’s repeated in both directions lies. Therefore, in the case of the basic cosine function, f(x) = cos(x), the period is 2π.

What is the domain of cosine and sine?

all real numbers
The domain of the sine and cosine functions is all real numbers. The range of both the sine and cosine functions is [−1,1]. The sine and cosine of an angle have the same absolute value as the sine and cosine of its reference angle.

### What is the range of Cos function?

−1 ≤ cosx ≤ 1
The function f(x) = cosx has all real numbers in its domain, but its range is −1 ≤ cosx ≤ 1. The values of the cosine function are different, depending on whether the angle is in degrees or radians. The function is periodic with periodicity 360 degrees or 2π radians.

What is the period of a cosine and sine function?

The period of a sinusoid is the length of a complete cycle. For basic sine and cosine functions, the period is 2π.

What is a period of a function?

The time interval between two waves is known as a Period whereas a function that repeats its values at regular intervals or periods is known as a Periodic Function. In other words, a periodic function is a function that repeats its values after every particular interval.

## What is the period of the function?

The distance between the repetition of any function is called the period of the function. For a trigonometric function, the length of one complete cycle is called a period. For any trigonometry graph function, we can take x = 0 as the starting point.

What is a period in trig?

Period of a Trigonometric Function The distance between the repetition of any function is called the period of the function. For a trigonometric function, the length of one complete cycle is called a period. For any trigonometry graph function, we can take x = 0 as the starting point.

How do you find the period of a cosine function of the form y Cos BX?

The period of a sine or cosine function is found by the equation p = 2pi/b or b = 2pi/p.
