Given or the following are true:

- a constant, doesn't really do much when graphing these functions, for some other trig ratios, gives the amplitude, that is not applicable with the tangent or cotangent

provided you know the definitions of all these terms, these rules aid you in graphing the trig function

Given or , the following are true:

Pretty much everything above i sthe same, except the period. for these functions, the period is

The graph of these functions will look like their original functions, except, you have to apply these conditions (that is, you may need to change the period by stretching the graph, or whatever)
