Question 01 (a)
Multiple Choice Question: Exactly ONE of the answers provided is correct. There is no partial credit in this questions.
To which of the following integrals does the Fundamental Theorem of Calculus apply?
v. None of the above.
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you?
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it!
The Fundamental Theorem of Calculus only applies to functions that are continuous on the entire domain of integration.
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.
- If you are stuck on a problem: Read the solution slowly and as soon as you feel you could finish the problem on your own, hide it and work on the problem. Come back later to the solution if you are stuck or if you want to check your work.
- If you want to check your work: Don't only focus on the answer, problems are mostly marked for the work you do, make sure you understand all the steps that were required to complete the problem and see if you made mistakes or forgot some aspects. Your goal is to check that your mental process was correct, not only the result.
Found a typo? Is this solution unclear? Let us know here.
Please rate my easiness! It's quick and helps everyone guide their studies.
Following the hint we check if the integrands above are continuous on the entire domain of integration.
i. Since is not even defined for negative numbers, the integrand is certainly not continuous on .
ii. The integrand is not defined for x=0, so it is certainly not continuous on .
iii. Since is not even defined for negative numbers, the integrand is certainly not continuous on .
iv. Here the integrand is defined everywhere. As a composition of continuous functions, the integrand is continuous. Hence the Fundamental Theorem of Calculus applies here.
Final answer: iv.
