Some improper integrals cannot be evaluated directly, so a student compares them with a chosen integral. That approach uses the:
AComparison theorem
BBinomial theorem
CChain theorem
DMean value theorem
Answer & Solution
Correct answer: A. Comparison theorem
1. Another integral is chosen carefully.
2. Convergence is judged by comparison.
3. It is the comparison theorem.
