What is the period of some trig functions?
periods of trigonometric functions. The values of some mathematical functions repeat with the same pattern to infinity. A function with this property is called a periodic function. A function ƒ: A → B is a periodic function if it satisfies the rule. ƒ (x + T) = ƒ (x) for all values of x in A. The number T is called the period of the function.

What is the period in a sine function?
The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.

Period of Trigonometric Functions
From the definition of the basic trigonometric functions as x x x - and y y y -coordinates of points on a unit circle, we see that by going around the circle one complete time ( ( ( or an angle of 2 π), 2\pi), 2π), we return to the same point and therefore to the same x x x - and y y y -coordinates.
Amplitude of Trigonometric Functions
As we have seen, trigonometric functions follow an alternating pattern between hills and valleys. The amplitude of a trigonometric function is half the distance from the highest point of the curve to the bottom point of the curve:
What is trigonometry in math?

What is frequency in science?
As such, frequency is a rate quantity which describes the rate of oscillations or vibrations or cycles or waves on a per second basis.
Is period a reciprocal of frequency?

What is frequency in math?
Frequency is how often something happens per unit of time (per "1").
What is the period of a sine function?
The period of the sine function is 2π. This means that the value of the function is the same every 2π units. Similar to other trigonometric functions, the sine function is a periodic function, which means that it repeats at regular intervals. The interval of the sine function is 2π. For example, we have sin (π) = 0. If we add 2π to the input of the function, we have sin (π + 2π), which is equal to sin (3π). Since we have sin (π) = 0, we also have sin (3π) = 0. Every time we add 2π of the input values, we will get the same result.
Does the coefficient of x matter when calculating the period?
This formula works even if we have more complex variations of the sine function like . Only the coefficient of x matters when calculating the period, so we would have:
What is periodic trigonometric function?
A function is called periodic if it repeats itself forever in both directions. The sine function like the one below is known as a periodic trigonometric function. When a function is periodic as the sine function is, it has something called a period.
How to find period of a function?
For example, consider the function f ( x) = 3sin (π x + 1) - 7. To find the period of this function, we first identify B, which is the number in front of x - or, in this case, it's π. Next, we simply plug B = π into our period formula.
Why is the period of sine function important?
Since this function is used so often to model real world phenomena, it's great to be able to identify this characteristic of the function in order to better analyze real world phenomena.
What is sine function?
Sine functions are often used to represent population patterns, weather patterns, and many other real-world phenomena. For example, suppose a particular forest has a rabbit population that can be modeled using the function R ( x) = 9200sin ( (π / 2) ( x) + (π / 2)) + 10000, where x is time in months.
How many units does a period of a function repeat?
We get that the period of the function f ( x) = 3sin (π x + 1) - 7 is 2, and that tells us that one cycle of the function repeats itself every 2 units forever in both directions.
Is a period a sine function?
Because the function is a sine function, we know that it's periodic. Any idea as to what the period of this function represents? Well, let's think about it. The period of the function is basically the length of the cycle that's repeated over and over again. Therefore, in this context, it would represent how long one cycle of breeding patterns, or population patterns, of these rabbits is. Well, that would be interesting to know. Let's figure it out.
