Solution
The image you have uploaded contains a set of 14 limit problems under the title "Latihan Soal." Let me provide solutions to a few of these problems with detailed steps.
Problem 1:
Solution:
- As , and .
Thus, the limit is:
Problem 2:
Solution:
- As , .
Thus, the limit is:
Problem 3:
Solution:
- As , and , so .
Thus, the limit is:
Problem 4:
Solution:
- Use the fact that and .
Thus, the limit becomes:
Problem 5:
Solution:
- Again, use .
Thus, the limit becomes:
Do you want further explanations or solutions to more of these problems? Here are some relative questions for you:
- How do you evaluate limits when the function involves a trigonometric identity?
- What are common limit rules used in calculus, especially for trigonometric limits?
- How does L'Hôpital's Rule apply to limits with indeterminate forms like ?
- What is the small-angle approximation for trigonometric functions, and how is it useful in limits?
- Can limits always be calculated directly, or do you sometimes need additional techniques (like series expansions)?
Tip: When dealing with trigonometric limits, remembering that and simplifies many problems.
