# What is the period of y cos x 4?

## What is the period of y cos x 4?

For your specific question, y=cos4x , the amplitude would be 1 and the period would be 2π4 , or π2

## How do you find the period of Cos x 4?

Find the period of cos(x4) cos ( x 4 ) . The period of the function can be calculated using 2π|b| 2 π | b | .

## What is the phase shift of Cos x PI 4?

Phase shift: c=π4 , function is shifted to the left.

## What does Y cos X mean?

Graphing y cos x The fact that the cosine function repeats itself means that that it is periodic. In particular, y cos x is periodic with period 2u03c0 . This means that if the point (x, y) lies on the graph, then the point (x+2ku03c0, y) will also lie on the graph where k is any integer.

## What is the period of Y cos X?

Find the period of cos(x4) cos ( x 4 ) . The period of the function can be calculated using 2u03c0|b| 2 u03c0 | b |

## What is the period of Y cos2x?

Period would be 2π2 or π .

## What is the period of a COS X graph?

Graphing y = cos x

In particular, y = cos x is periodic with period  .

## What is fundamental period of Cos 4x?

Therefore, the period would be 2πB. For your specific question, y=cos4x , the amplitude would be 1 and the period would be 2π4 , or π2

## How do you find the period of Cos X?

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 2u03c0

## How do you find the period of Cos x 2?

A function is periodic if f(x)f(x+T). As we can see, T is dependent on the value of x and hence, is not a constant. So cos(x2) is not periodic.

## What is the period of cos X function?

period 2π
The fact that the cosine function repeats itself means that that it is periodic. In particular, y = cos x is periodic with period  .
