This course was really amazing full of knowledge and skills which I was looking for regarding my master's studies. thank you once again to the dtu and its staff for offering this prestigious course.
常見問題
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
What is the refund policy?
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
Is financial aid available?
Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left. You’ll be prompted to complete an application and will be notified if you are approved. Learn more.
Aerodynamics, how to find the right values of a and a'?
1.The formula for finding x = ({Omega}* R )/v_0
2.Solve[16 a^3 - 24 a^2 + a (9 - 3 x^2) - 1 + x^2 == 0, a]
3. a is in interval (0<a<1)
4. a' = (1 - 3 a)/(4 a - 1)
How many numbers after comma I should enter?
Coursera takes in unlimited about of numbers after comma, but we suggest you enter by approximation of 0.01, in cases where the answer is larger then 10000, the decimals are not necessary.
Economics: Having problems with negative values!
All answers are asked to be entered in absolute value.
Economics: I am having problems with calculating NPV!
You have included the present value of the decommissioning cost in the NPV calculation. We have not asked you to do that, so that is why answer is outside the range, but including these costs could also be done, so you are not entirely wrong.
