If the period of a cosine function is 1/3 what is the frequency of the function?
Well, if the period of a cosine function is 1/3, it means that it completes one full cycle every 1/3 unit of time. So, to find the frequency, we need to flip that fraction over. This means that the frequency of the function is 3 cycles per unit of time. And that's a frequency you can really groove to!
To find the frequency of a cosine function when given the period, you can use the formula:
frequency = 1 / period
In this case, the given period is 1/3. Plugging this value into the formula, we get:
frequency = 1 / (1/3)
= 3
Therefore, the frequency of the cosine function is 3.
