We can have all of them in one equation: y = A sin(B(x + C)) + D. amplitude is A; period is 2 π /B; phase shift is C (positive is to the left) vertical shift is D; And here is how it looks on a graph: Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation.

Frequency is the number of times a particular value occurs in a set of data. Usually we would record the frequency of data in a frequency table. Example: Using the key: H = Hockey, B = Badminton, F = Football, each letter below indicates a student joining the sports club. H H B F B H F F H B.
Relative frequency is the number of times an event happens divided by the total number of outcomes that took place in an experiment, known as the number of trials. To calculate the relative frequency we can use the formula, \text{Relative frequency = }\frac{\text{frequency of event occurring}}{\text{total number of trials of the experiment}}
The frequency formula is used to find the frequency of a wave. Frequency is defined as the number of cycles completed per unit time. It also tells about how many crests go through a fixed point per unit time. Sometimes it is known as reciprocal of time. Frequency is expressed in Hertz (Hz).
