The curve representing a graph of a cosine function (y=cosx) is called a Cosine Wave. A Cosine Graph on the Number Line. A cosine wave on the 0 to 2π interval.
Given that we are using a cosine function, we know that the peak of the wave occurs when the argument of the cosine (i.e. the total phase) is an integer multiplied by \(2\pi\). We will make it easy on ourselves by just choosing zero.
