is of type and therefore equals .
Example 40 __
(Example 13) is of type and thus equals , as before. Note
that is not the limit of an indeterminate form!
Example 41 __
is of type and therefore equals .
Example 42 __
(Example 20) is of type , so that it equals , which is
again of type . Apply L’Hôpital’s Rule twice more:
For this problem, it is easier and faster to apply the Rational Function Theorem!
