In words:
- the 2 tells us it will be 2 times taller than usual, so Amplitude = 2
- the usual period is 2 π, but in our case that is "sped up" (made shorter) by the 4 in 4x, so Period = π/2
- and the −0.5 means it will be shifted to the right by 0.5
Is amplitude same as period?
Amplitude—maximum displacement from the equilibrium position of an object oscillating around such equilibrium position; Frequency—number of events per unit of time; Period—time it takes to complete one oscillation; For waves, these variables have the same basic meaning.
What is the formula for finding period?
Listed below are three main aspects to finding the formula for period:
- Find if it is a periodic function i.e. if the function repeats over at a constant period
- If the formula for period function is represented like f (x) = f (x + p), where p is the real number
- Period means the time interval between the two occurrences of the wave
What is the amplitude, period, and midline of the function?
We know that the standard functions (f(t) = sin(t)) and (g(t) = cos(t)) are circular functions that each have midline (y = 0text{,}) amplitude (a = 1text{,}) period (p = 2pitext{,}) and range ([-1,1]text{.}) Our work in Preview Activity 2.4.1suggests the following general principles.
How do you find the period of the frequency?
Calculate the period of oscillations according to the formula above: T = 2π√ (L/g) = 2π * √ (2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!

How do I find the period of a function?
We can always calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin (B a – c) and y = A cos ( B a – c ) is equal to 2πB radians. The reciprocal of the period of a function is equal to its frequency.

What is period and amplitude?
Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat.
What is the period of a wave formula?
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.
What is the amplitude of a function?
Explanation: The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine.

How do you find the period of a function without graphing?
The period is defined as the length of one wave of the function. In this case, one full wave is 180 degrees or radians. You can figure this out without looking at a graph by dividing with the frequency, which in this case, is 2.

What is the period of a graph?
Any one full pattern in the graph is called a cycle, and the length of an interval over which a cycle occurs is called the period.
What is a period in a wave?
Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.
What is the period of f θ )= sin θ?
2 pi1 Answer. The period of f(t) = sin t is 2 pi .
What is the period of a graph?
Any one full pattern in the graph is called a cycle, and the length of an interval over which a cycle occurs is called the period.
Why is the period 2pi B?
It means the period is 12, so each cycle is 12 units long. What you say is sort of right: b is the number of cycles per 2pi.
What is the period of a COS 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.

Therefore, the only graph with amplitude 3 and period {eq}dfrac {pi} {2} {/eq} is graph C.
What is the amplitude of a sine function?
Amplitude: The amplitude of the graph of a sine function is the vertical distance from the top of a peak to the center line. This is the same as the vertical distance from the top of a peak to the lowest point on the graph, divided by 2.
What is the midline of a sinusoidal graph?
What are midline, amplitude, and period? Midline, amplitude, and period are three features of sinusoidal graphs. is the horizontal line that passes exactly in the middle between the graph's maximum and minimum points. is the vertical distance between the midline and one of the extremum points.
What can we analyze for sinusoidal function?
Given the graph of a sinusoidal function, we can analyze it to find the midline, amplitude, and period. Consider, for example, the following graph.
What is the horizontal line that passes exactly between the maximum and the minimum value?
The horizontal line that passes exactly between (the maximum value) and (the minimum value) is , so that's the midline . The vertical distance between the midline and any of the extremum points is , so that's the amplitude. The distance between the two consecutive maximum points is , so that's the period.
How to find the amplitude of a trough?
The amplitude, A, is found by taking half the vertical distance between the peaks and the troughs.
What does a bigger amplitude mean?
In light waves – a kind of electromagnetic radiation – a bigger amplitude means a brighter light. Radio is often broadcasted using AM or Amplitude Modulation transmissions, meaning information can be picked up by a receiver tuned to the correct amplitude of the waves. 2. Period.
What does higher frequency mean in sound?
A higher frequency means more oscillations per second, so on a graph, the waves look closer together. A higher frequency means more oscillations per second, making the waves look closer together. In soundwaves…. The higher the frequency, the higher pitched the sound.
How to find frequency of a wave?
So, to find the frequency of a wave first find the period like we showed you above , then take its reciprocal to find the frequency.
What are the attributes of a function?
This is what it looks like on a graph. These functions have 5 main attributes, which are also called transformations. 1. Amplitude. The amplitude of a wave is the greatest displacement from the rest position. The bigger the amplitude , the taller the wave. In sound waves, a bigger amplitude means a louder sound.
What is the term for a wave measured with time?
It can be called the time period and has the symbol, T. The word period is used for waves measured with time. If the measurement is distance, it is called the wavelength. The period of a wave is closely related to its frequency.
How to make a sound twice as loud?
Think of it this way: a sound will be twice as loud if you doubled its amplitude. Multiplying the whole function by 2 is doubling the amplitude.
