Math Problem Statement
Solution
The given expression is:
Let's solve this limit step by step:
Step 1: Evaluate directly at
Substitute into the function:
This results in an indeterminate form , so we need to apply L'Hôpital's Rule or simplify the expression further.
Step 2: Apply L'Hôpital's Rule
L'Hôpital's Rule states that for indeterminate forms like , we can differentiate the numerator and the denominator and then take the limit.
-
The derivative of the numerator is:
-
The derivative of the denominator is:
Now the limit becomes:
Step 3: Evaluate the new limit
Substitute into the new expression:
Final Answer:
The limit is:
