Take a look at the applet
The graph of the function is a sinusoid. That is a graph that results when you transform the graph of a standard sine function . The graph of has the following properties:
the amplitude (maximum deviation from the equilibrium) is ;
the period is so ;
the horizontal translation is ;
the equilibrium is the line .
