How do you find the frequency of a sine wave?

In a sinusoidal model of the form y = a⋅sin(b(x−c))+d , the period is found by taking 2⋅π|b| . Frequency is the reciprocal of period. Example: y = 2⋅sin(3x) would have a period of 2π3 , which is one-third the length of the "normal" period of 2π .

How do you find the frequency of a trigonometry?

We'll plot the function and then measure the period, which is the distance between two identical and consecutive portions of a curve. Then we'll take the reciprocal of the period to obtain the frequency.

What is the wavelength of a sine wave?

In a sine wave, the wavelength is the distance between peaks. In the diagram above, the wavelength is the distance from 1 to 2, or the distance from 3 to 4. Any one of these distance measurements would suffice in determining the wavelength of this wave. Wavelength is commonly designated by the greek letter λ.

What is period of sin?

The period of the sine function is ​2π​, which means that the value of the function is the same every 2π units.
