# What is the amplitude and period of sine?

## What is the amplitude and period of sine?

Every sine function has an amplitude and a period. 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 amplitude of sin?

The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In other words, the amplitude is half the distance from the lowest value to the highest value.

#### How do you find the period of Sinx?

We have a really easy way to determine the period of the sine function. If we have a sine function of the form f(x) = Asin(Bx + C) + D, then the period of the function is 2π / |B|.

**How do you find the 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. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

**What is the period of sin?**

2π

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.

## How do you find period and amplitude?

### How to find the amplitude and period?

To find the amplitude, simply look at a. In this case, the amplitude is 3, since it is the number before tan and takes the spot of a. To find the period, divide π by b (π /b = period). Find your b value, and put π over it, like so: π /4. 4 is b in this example, and since there is no way to simplify that, the period is π /4.

#### How do you determine amplitude?

Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the amplitude will measure the loudness of the sound.

**How to find amplitude Cos?**

Trigonometry. Find Amplitude, Period, and Phase Shift y=cos (x) y = cos (x) y = cos ( x) Use the form acos(bx−c)+ d a cos ( b x – c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 1 a = 1. b = 1 b = 1. c = 0 c = 0. d = 0 d = 0. Find the amplitude |a| | a |.

**What is the midline of a sine function?**

The midline is the average value. Sinusoidal functions oscillate above and below the midline, are periodic, and repeat values in set cycles. Recall from Graphs of the Sine and Cosine Functions that the period of the sine function and the cosine function is 2π. In other words, for any value of x,
