  • Remark from the TA on HW2:
    I chose question 1, 3, 4, 7, 8 and 9. (Two point for each problem, and 8 points for completeness.) Students usually have difficulties in forming an ODE in question 1; for the question 3 and 4, many students think that phi(x,y) is the general solution of ODE while y(x) should be; for the question 9, some students have problems in finding the limit by using the diagram.

  • Remark from the TA on HW1:
    The grading is over 20 points: Problems 1-3, 6-10 had value of 1 point each. Problems 11-12 had value of 2 points each and problems 4-5 had value of 4 points each.
