Try doing something similar to what was done in the example problems 4.7, 4.8 and 4.9. Also, since this assignment has already been graded, you have access to the full solutions. Just go to the assignment using the same link you used to submit your homework and you'll be able to see your grade, feedback, and the full solutions.
