Sine, cosine and tangent functions are periodic functions, meaning they repeat themselves at regular intervals. This interval of repetition is known as the period of the function, and this periodicity ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has been ...

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...
