VERTICAL ASYMPTOTES


               The tangent function has something called vertical asymptotes, which are

               invisible vertical lines that the function approaches, but never crosses. To find the
               two consecutive vertical asymptotes of a tangent function you can solve the two
                                                      
               equations      = −  and       =

               Consider the graph of the function    = tan 0.5  





















               You can see from the graph that there are vertical asymptotes at −   and   . You

               could have also used the equations to obtain this information.

               0.5   = −      = −     and  0.5   =    =
