          Graphs of the Sine and Cosine Functions

               Characteristics of Trig Functions
     ­ all trig functions repeat themselves, the horizontal distance it takes for 
                              .
                          period
     the graph to repeat itself is called the 
                                 .  It is defined as half 
                           amplitude
     ­ the sine and cosine functions have an 
     the distance between the maximum and minimum values.
                        For the basic sine function
                        period =
                        amplitude =  
                       For the basic cosine function
                       period = 
                       amplitude =

              The sine & cosine graphs can be changed to any size wave by 
              changing some things in the equation. Right now we are going to 
              concentrate on amplitude and period.
                                              amplitude
                                             = period

     Example
           Identify the amplitude and period from the equations
