Question 01 (i) |
---|
Calculate the derivative if |
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 fundamental theorem of calculus.
|
Hint 2 |
---|
Remember that the Fundamental Theorem of Calculus says (where a is any fixed real number). |
Hint 3 |
---|
The integral given in this problem has a function of x in both bounds (top and bottom). You can split the integral into two parts to obtain the form in the previous hint. |
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.

Please rate my easiness! It's quick and helps everyone guide their studies. Using the fundamental theorem of calculus, we have where in the last equality on the right most sum, we used the chain rule to compute the derivative. This completes the question. |
