Observe the graph:
\As ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
tends to ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=187cf36b069ebb2e95071762f5907729.png\")
, the function value increses and decrases rapidly.
From the graph there is no conclusion.
\Therefore, the limit does not exist.
