Question 01 (a) 

Which of the following is equal to ? (A) (B) (C) (D) 
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 hints below. Read the first one and consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! If after a while you are still stuck, go for the next hint. 
Hint 1 

Use the chain rule 
Hint 2 

Use the fundamental theorem of calculus. 
Checking a solution serves two purposes: helping you if, after having used all the hints, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Solution 1

Please rate my easiness! It's quick and helps everyone guide their studies. Let be an antiderivative of . Setting this means that . By the fundamental theorem of calculus it holds that . Hence, applying the chain rule first and then the fundamental theorem of calculus we find that The correct final answer is A. 
Solution 2 

Found a typo? Is this solution unclear? Let us know here.
Please rate my easiness! It's quick and helps everyone guide their studies. Alternatively, notice that
The final answer is A.
