Math Problem Statement
Solution
The limit in the problem you've shared is:
We will use algebraic techniques to simplify and solve this limit. First, let's check what happens if we directly substitute .
Direct substitution:
This doesn't yield an indeterminate form like or , so the limit can be calculated directly.
Thus, the answer is:
For further simplification, if you rationalize the denominator:
So, the simplified result of the limit is:
Would you like more details on any step? Here are some related questions:
- How do you simplify radicals in the denominator?
- What is rationalizing the denominator, and why is it used?
- Can L'Hôpital's rule be applied here? If so, how?
- How do limits behave when direct substitution works?
- What are indeterminate forms and when do they occur in limits?
Tip: Always check the form of the expression when taking limits to decide whether direct substitution, factoring, or rationalizing is appropriate.
