How do you find the period of a waveform?
- The formula for period is T = 1 / f where “T” is period – the time it takes for one cycle to complete and “f” is frequency.
- To get period from frequency first convert frequency from Hertz to 1/s.
- Now divide 1 by the frequency. The result will be time (period) expressed in seconds.

What is Formula for Period?
According to the definition of a period of a function, a function f (x) will be periodic with period p, so if we have f (x + p) = f (x), for every p > 0. The period of each of sin x, cos x, csc x, and sec x = 2π. The period of each of tan x and cot x = π. The period of the wave decreases as its frequency increases. Here is the formula for period (T) of a trigonometric function:
How to find period of a wave?
The formula for the period is used to calculate the time period of a wave. It is the time taken by a wave to reach from one peak to another. A periodic function is defined as a function that repeats its values at regular intervals or periods. The period of a function f (x) is p, if f (x + p) = f (x), for every x. Let us learn about the formula for the period with a few solved examples in the end.

What is period in a trig function?
The period is defined as the length of a function's cycle. Trig functions are cyclical, and when you graph them, you'll see the ups and downs of the graph and you'll see that these ups and downs keep repeating at regular intervals. All you have to do is to follow these steps.
How to tell period of wave?
If you look at a graph, you can see that the period (length of one wave) is . Without the graph, you can divide with the frequency, which in this case, is 1.
What is the best bet for periodic function?

Where does the minimum occur on a graph?
The minimum occurs in the middle of the graph , so to figure out where it starts, subtract from the minimum's x-coordinate:
How are frequency and period related?
As previously stated, the frequency and period of a wave are closely related. Frequency describes how often, or how frequently, a wave will go through its cycle in a given amount of time , while period describes how long it takes for a wave to complete one cycle. Therefore, if a wave has a shorter period, meaning it can complete a cycle in a short amount of time, then more cycles can pass in a given timespan, thus increasing the frequency. In other words, with a lower period, a wave will have a higher frequency and vice versa. In the math world, these two are said to be inversely proportionate with one another, where the value of one goes up while the other goes down.
What is the Period of a Wave?
Waves are also present in ways that their structure can not be seen from the naked eye, like sound waves or electromagnetic waves (light). They have specific properties that make them unique: a high point and low point that oscillate in a continuous cycle .
How to find frequency of a wave?
Frequency can be found by taking the velocity of a wave ( {eq}v {/eq}) and dividing it by its wavelength ( {eq}lambda {/eq}):
What is the distance between a peak and a trough?
This continuous cycle is called the wave cycle, and it is defined as a wave's peak to peak, or trough to trough, where a peak, or crest, is the high point of the wave and a trough is the lowest point of the wave. The distance between a wave's peak to peak or trough to trough is the same and is also known as the wavelength because it measures the length of the wave cycle.
How many cycles does a wave have?
Since the wave can complete one cycle in two seconds, then it would complete five cycles in ten seconds. This means that the wave has a frequency of five cycles over a timespan of ten seconds. However, frequency is typically measured in the number of cycles that occur over just one second, so this wave's frequency would be one-half cycles per second. In other words, this wave can only complete half of its cycle in one second.
How long does a wave cycle last?
The wave has a period of 1/3, meaning it completes a full cycle in only one-third of a second.
How to find period of a function?
To find the period of f ( x) = A cos ( Bx + C) + D, we follow these steps: 1 Identify the coefficient of x as B. 2 Plug B into 2π / | B |. This is the period of the function.

We see that the period of the function g ( x) = 3cos (8 x + 1) is π / 4.
What does the period of a cosine function represent?
In this scenario, do you see what the period of the function would represent? The period represents one cycle of the cosine function that repeats itself over and over again. Thus, in this example, the period would represent one cycle of the spring going from its highest, or most compressed position, to its lowest, or most stretched position, and then back to its highest position. Is that what you were thinking? You're definitely getting the hang of this, pun intended!
What is the interval of a 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.
Is a cosine function a periodic function?
If we look at the cosine function from x = 0 to x = 2π, we have an interval of the graph that's repeated over and over again in both directions, so we can see why the cosine function is a periodic function.

How long does it take for a male egg to be fertilized?
In this phase, the egg is released into the fallopian tube. Once it is released, there is a 24-48 hour window during which it could be fertilized by male sperm. Cervical mucus increases during this time, to help the sperm swim up to the egg. If the egg is not fertilized, the lining begins to break down and the next phase begins.

What is the difference between a short period and a long period?
A short period means the investment breaks even or gets paid back in a relatively short amount of time by the cash flow generated by the investment, whereas a long period means the investment takes longer to recoup. How investors understand that period will depend on their time horizon.
Why is it important to calculate payback period?
Calculating payback periods is especially important for startup companies with limited capital that want to be sure they can recoup their money without going out of business. Companies also use the payback period to select between different investment opportunities or to help them understand the risk-reward ratio of a given investment.
What is a Payback Period?
The payback period is the amount of time it will take to recoup the initial cost of an investment, or to reach its break-even point. This is one of the most important calculations for investors when planning investments and returns. It can help investors decide between different investments that may have a lot of similarities, as they’ll often want to choose the one that will pay back in the shortest amount of time.
Why is the payback period shorter?
Another limitation of the payback period is that it doesn’t take the time value of money (TVM) into account. The time value of money is the idea that cash will be worth more in the future than it is worth today, due to the amount of interest that it can generate. Not only does this apply to the initial capital put into an investment, but it’s also important because as an investment generates returns, that cash can then be reinvested into something else that earns interest or income. This is another reason that a shorter payback period makes for a more attractive investment.
Is a longer payback period acceptable?
If earnings will continue to increase, a longer payback period might be acceptable.
Does the payback period take into account other ways an investment might bring value?
The payback period doesn’t take into consideration other ways an investment might bring value, such as partnerships or brand awareness. This can result in investors overlooking the long-term benefits of the investment since they’re too focused on short-term ROI.
