Key features of the tangent function

               AMPLITUDE

               Amplitude does not apply to the tangent function since there aren’t any minimum

               or maximum values.

               PERIOD


               Consider the tangent function in the form    =    tan     .  To determine the period
                      
               use  . Below is the graph of    = tan   , notice that the tangent function repeats
                      
               every π units.























               Now look if we graph the function    = tan 2  






















                                                                   
               Notice now that the function repeats every  units.
                                                                 2
