# How do you calculate the frequency of the rotation of the Earth?

Observe a star at night when it comes above your head(altitude 90degree)..Me sure the time when it comes above your head next night.The difference will be the time for one rotation.

Since the earth rotates by about one degree around the sun, the rotation time calculated using the sun's rotational speed is incorrect; the earth actually rotates in 23 hours, 56 minutes, and 4 seconds.

The frequency of the rotation of the Earth can be calculated using the formula: Frequency = 1 / Period of Rotation. The period of rotation of the Earth, also known as the sidereal day, is approximately 23 hours, 56 minutes, and 4.1 seconds. Therefore, the frequency of the Earth's rotation is approximately 0.0000727 hertz (Hz), or 1 rotation every 23 hours, 56 minutes, and 4.1 seconds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
