Math Problem Statement
Solution
The given problem is:
Let's proceed step by step to solve the limit.
Step 1: Simplify the expression
First, express as: Now, the limit becomes:
Step 2: Analyze the behavior as
As :
- ,
- ,
- .
This suggests the limit might be an indeterminate form , so we can apply L'Hopital's Rule.
Step 3: Apply L'Hopital's Rule
We apply L'Hopital's Rule, which states that if a limit is in the form or , we can take the derivatives of the numerator and denominator and then compute the limit again.
The expression is: We differentiate the numerator and denominator with respect to .
-
Derivative of the numerator is: At , this becomes .
-
Derivative of the denominator is: At , this becomes .
Step 4: Compute the limit
Now, applying L'Hopital's Rule: Simplifying:
Thus, the value of the limit is 0.
