.

1.  If "x" approaches   from the left side,  tan(x) tends to  "+ infinity".



2.  If "x" approaches   from the right side,  tan(x) tends to "- infinity".



3.  So the function  y = tan(x)  is not a continuous function at  .



4.  In general case, if the sequence    approaches to    in a way that the values of    lie in both sides of the value  ,

    then the sequence    HAS NO limit.
