Question 03 (c) |
---|
Calculate the following derivative. You may leave your answer unsimplified. , where . |
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 |
---|
You need to use the quotient rule and one other rule to calculate this derivative. |
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. To begin calculating this derivative, apply the quotient rule. So
The derivative of 3x is simple to calculate, but in order to calculate we will need to use the chain rule as follows:
Plugging this back into the quotient rule, we get:
You can leave this answer as is. |
