The rational function has the horizontal asymptote ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c3f40df3b6ee26c4ed5b179d6afd8b20.png\")
.
Horizontal asymptote is the ratio of leading coefficient of numerator and denominator,when the degree of the numerator is equal to the degree of the denominator.
\Here the horizontal asymptote ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c3f40df3b6ee26c4ed5b179d6afd8b20.png\")
is like ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4884b984099476cdb9745d5a43eef021.png\")
.
Therefore, the degree of the numerator is equal to the degree of the denominator of the rational function.
