Solution
Let's apply L'Hôpital's Rule to evaluate the limit.
Given limit:
First, simplify the expression:
As we discussed earlier, directly substituting gives a division by zero, indicating that L'Hôpital's Rule may be applied. L'Hôpital's Rule states that if a limit results in an indeterminate form like or , we can evaluate the limit of the derivatives of the numerator and denominator.
Differentiate the numerator and the denominator separately with respect to :
- The derivative of the numerator is .
- The derivative of the denominator is also .
Now, apply L'Hôpital's Rule:
Thus, the limit is:
