## 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.
