Question 01 (h) 

Evaluate . 
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! 
Hint 

Note that you can write and that is the derivative of , Also, given this can be written in terms of . Try a substitution. 
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.

Please rate my easiness! It's quick and helps everyone guide their studies. Following the remark in the hint, we begin by factoring out , the derivative of so that we can later do a substitution. In doing this substitution, we will need to express the integrand in terms of powers of with a single factor of .
With , giving
