what is period of a cosine function

what is period of a cosine function The period of the cosine function in its basic form latex y cos x is 2 This period can be modified by multiplying the variable x by a constant We can reduce the period of the function by multiplying x by a number greater than 1

To recap the period of a standard cosine function represented as y cos x is 2 pi This is true for all cosine functions that aren t affected by a horizontal stretch or compression When the function takes the form y A cos B x C D the period can be calculated using the formula T frac 2 pi B What is the period of a cosine function Learn the graph and equation of a cosine function Understand how to find the period of a cosine function with examples Updated 11 21 2023

To write a sine function you simply need to use the following equation f x asin bx c d where a is the amplitude b is the period you can find the period by dividing the absolute value b by 2pi in your case I believe the frequency and period are the same c is the phase shift or the shift along the x axis and d is the vertical Period 3 Frequency 6 Explanation Our equation is in the form y A sin fx h k where A is the amplitude f is the frequency h is the horizontal shift and k is the vertical shift We can look at the equation and see that the frequency f is 6 The period is 2 f so in this case 2 6 3

What is the Period of Cosine Function A period of a function is when the function has a specific horizontal shift P which results in a function equal to the original function i e f x P f x for all values of x within the domain of f The period of the cosine function is 2 Is the Cosine Function Even or Odd 3 The period of a sine or cosine function is the distance between horizontal intercepts 4 The amplitude is the vertical distance between the maximum and minimum values 5 The midline of the cosine graph is the vertical line 180 6 The cosine graph looks just like the sine graph except flipped upside down

One period of cos x is 2 but one period of cos 2x is In other words period is descriptive of a specific function not of whatever function you perceive to be the underlying function B used to determine the period of the function the period of a function is the distance from peak to peak or any point on the graph to the next matching point and can be found as In y cos x the period is 2 We can confirm this by looking at the peaks in the cosine graph At x 0 y cos x has a peak
