  • Homework Assignment 1
    Grading Policy this time: If you worked on #1 (a)-(d), regardless whether correct or incorrect, 1 point each. Same with #4 (a)-(c). For #2 (a)-(f), 3 points each for having the right statement and 10 points in total for the proof technique presented. For #3, 5 points for the correct structure of the proof and 10 points for the correctness of the proof. The scores are posted.

  • Homework Assignment 2
    Grading Policy this time: Each problem #5 - #9 was ten points. The scores are posted.

  • Homework Assignment 3
    Grading Policy this time: Problem #10 was 10 points, #11 and #12 together 10 points, #15 was 10 points, #17 was 10 points, and #18(b) was 10 points. If you didn't work on the other problems, I deducted up to two points per problem. The scores are posted.

  • Homework Assignment 4
    Grading Policy this time: Each problem part was 2.5 points (there were 20 parts alltogether). The scores are posted.

  • Midterm Exam 1 Solutions
    It's graded and the results are posted. The average is 67.4 points (out of 80), that's 84.25%.

  • Homework Assignment 5
    Grading Policy this time: Problems #27 and #32 were 10 points each, each part of #30, #31, and the correct limit in #33 was 2 points (15 parts). If you didn't work on the other problems, I deducted two points per problem. The scores are posted.

  • Homework Assignment 6 Don't miss this once-in-a-lifetime-offer of incredible 75 points!!
    Grading policy was as follows: Each part (a)-(o) was either completely correct (5 points), almost completely correct (4 points), almost completely wrong (1 point), or completely wrong (0 points). The total number of points was multiplied by five and divided by eight and this number was entered in the column for Homework 6. This number was also subtracted from the total number of points and the result was added to the amount in the extra credit column. The scores are posted.

  • Homework Assignment 7
    Grading Policy this time was very generous: If some part was missing or completely wrong, two points were deducted. The scores are posted.

  • Homework Assignment 8
    Everybody who prepared homework got 50 points this time (not too bad, huh?) Here are the updated scores.

  • Midterm Exam 2 Solutions
    It's graded and the results are posted. The average is 65.4 points (out of 80), that's 81.75%.

  • Homework Assignment 9 Deadline extended through Monday. How is it going? If you really want a further extension, here is what to do: Send me an e-mail telling me you would like to have a further extension (include a brief explanation why you want this extension). If I receive e-mails from at least ten Math 309 students by 10 pm tonight, I will extend the deadline through Wednesday. Here is the current number of e-mails I received until now: 12 (i.e., it's extended through Wednesday!).
    Grading Policy this time: Problems #48 and #49 were 10 points each, the remaining problems were 5 points each. The scores are posted.

  • Homework Assignment 10 On #59, find the integral of the inverse function of f. Write it as 1 times the inverse function of f and then integrate by parts. Then do a substitution and it should be okay.
    Grading Policy this time: Problems #55, 58, 60, and 61 were 10 points each, I took up to 10 points away if you didn't work on the remaining problems. The scores are posted.

  • Midterm Exam 3 Solutions
    It's graded and the results are posted. The average is 66.2 points (out of 80), that's 82.75%.

  • Homework Assignment 11 It's the last one!!! (Unless you will be taking Math 311 :)
    Grading policy this time: Everybody who turned in something got 50 points, click on the updated scores.

  • Final Exam Don't miss this! There will be 210 more points for you to collect. When? This coming Wednesday, 10:30-12:30! Where? In our usual room! The first problem will be: Find the infimum, mimimum, supremum, and maximum of a given set (including proving your claims). The second problem will be a proof by induction. The third problem will be: Define convergence and show that a certain sequence is convergent. The fourth problem will be: State a certain theorem and use it to show that a certain sequence is convergent. The fifth problem will be: Give the epsilon-delta criterion for continuity of a function and use it to show that a certain function is continuous at a given point. The sixth problem will be: State the definition for differentibility and use it to show that a certain function is differentiable at a certain point. The eighth problem will be: State the fundamental theorem of calculus (both parts) and use it to calculate the limit of a certain infinite sum. The seventh, ninth, and tenth problems are about the intermediate value theorem, infinite integrals, and uniform convergence. The problems are easy, but they have to be presented in a neat way, using the same format as presented in class. You have one page for each problem, and you also will receive extra paper for scratch work that will not be collected. The recommended procedure is to first use this extra paper for some preliminary calculations, then write down the solution neatly inside the designated area, then move to the next problem. Be aware that only this designated area (i.e., one page per problem) will be graded, and that even minor deviations of the allowed format will be punished with point deduction (each problem is worth 21 points). The final grades are posted! If you find anything wrong, let me know IMMEDIATELY as the final grades will be turned into the Registrar's office tomorrow morning 8 am.

I hope you all had a great semester, and if you are taking Math 311 SEE YOU NEXT YEAR!
