How To Graph Sine & Cosine Functions Using Transformations

Sine and cosine are both periodic functions, and have the same domain and range. They are separated only by a phase shift: . This is the constant that must be added to create the necessary horizontal shift to make the graphs directly overlap each other.

Graphing the Trig Functions Graphing Sine and Cosine General form for sine function (cosine has a similar form): y = A sin(bx — c) + d where A is the amplitude (vertical stretch or compression) of the function, b causes a change in the period (horizontal stretch or compression) of the function, c causes a phase shift (horizontal shift), and d is a vertical shift. Graph: y sin(x) Use a table

The “minus” sign tells me that the graph is upside down. Since the multiplier out front is an “understood” –1, the amplitude is unchanged. The argument (the 3x inside the cosine) is growing three times as fast as usual, because of the 3 multiplied on the variable, so the period is one-third as long.
