Announcements:
- Congratulations to those who did well, and good luck to everyone on their remaining final exams!
- Final exams graded, scores on Gradescope and Blackboard.
- MATLAB exams graded and on Blackboard, out of 5 points.
- Assigned final exam seats for Tuesday, Dec 18th in MR117 are at this link and a seat map is at this link.
- Exam 3 graded, results on Gradescope, scores on Blackboard.
- For the Matlab exam:
- There will be one student per computer.
- There will be access to the built-in MATLAB help and to the 203 MATLAB notes that we have been using, but no access to the web.
- Each student gets a printed one-page version of the exam, and makes an M-file to answer each question.
- When a question is answered, you can print the solution using "Publish to PDF" in MATLAB (as we did in Lab 2) and then printing to the printer in the Artino lab. You will need to make sure that your name and exam version are in your m-file and printout.
- Make sure to use semi-colons to suppress output of large matrices to avoid your printouts including many pages of numbers.
- Your printout will be brought to you, then you will staple your exam to your printout solutions and turn it in at the end of the seating.
- HW 8.5 and 8.6 have been re-opened to now be due Dec 7th since some students had difficulty accessing them.
- For the Matlab exam on Dec 11, last names A-M will have the 11:35 seating, and last names N-Z will have the 12:10 seating. We will have usual lecture beforehand from 10 to 11:30, reviewing material from vectors (August) to Taylor series (December).
- For exam 3, there will be two options:
- Get the whole exam at the beginning of class, and complete it in one sitting.
- Get the first half of the exam at the beginning of class. Turn it in and then take a 5 minute break at 10:50. Then get the second half of the exam and complete the second half in the remaining time.
If you expect to need to leave during the exam, you should opt for the two-part option. No student who arrives after 10:10am can opt for the two-part option. Bring photo ID, as usual. No one-part exam student may leave until 10:55.
- Exam 3 coming up, Dec 6. Understand all material up to 8.6, power series.
- Final exam room set to be Marshak 117, seats TBA.
- Exam 3 coming up, will cover up to Taylor series.
- We have done our last MATLAB lab of the term and since we are behind on lecture material, lectures will continue in the classroom instead of moving to the computer lab.
- Final exam will be Tuesday, Dec 18th in a room TBA. The registrar's page had it as Monday, Dec 18th until recently so please make sure you are not confused about the date and time.
- This grade estimator page may be helpful for planning and analyzing "what if" scenarios.
- MATLAB exam planned for Tuesday, Dec 11th, our last day of class. I expect there to be two seatings, one at 11:35 and one at 12:10.
- Exam 3 coming up, Thursday Dec 6th, will cover from multiple integrals through sequences and series.
- MATLAB quiz 8 apparently closed a little early, so it is open again until 11pm on Friday, Nov 16
- If you have three final exams on the same day and would like accommodation, it is your responsibility to let instructors know far in advance and the final schedule is available.
- Final exam is Monday, Dec 17th 1pm-3:15pm, see the registrar's final exam schedule
- Some students were having difficulty with Webwork assignments not being visible. Those should be sorted out and the deadlines have been extended a bit.
- For regrade requests on exam 2, check on Gradescope. I will do those the week of Nov 12th so those must be requested before Tuesday, Nov 13th.
- Tues, Nov 13 9am office hours cancelled. Check webpage above for updates.
- Tues, Nov 6 is the last day to withdraw from the course and get a W grade.
- Exam 2 scores on Blackboard.
- Exam 2 graded via Gradescope. You may need to sign up to see your exam if you have not used the system before, as indicated in the email sent.
- For students interested in getting their own copy of Mathematica, there are instructions at this link
- For those who have never seen a round pizza cut into square pieces, here is a picture.
- Blackboard quiz #6 is re-open for submissions after it ended early.
- A handout about symmetries and multiple integrals is here.
- For exam 2, there will be two options:
- Get the whole exam at the beginning of class, and complete it in one sitting.
- Get the first half of the exam at the beginning of class. Turn it in and then take a 5 minute break at 10:50. Then get the second half of the exam and complete the second half in the remaining time.
If you expect to need to leave during the exam, you should opt for the two-part option. No student who arrives after 10:10am can opt for the two-part option. Bring photo ID, as usual. No one-part exam student may leave until 10:55.
- Exam 2 coming up, Nov 1st. Understand all material up to 12.4, applications of double integrals.
- We will visit 13.6 a second time, this time talking about tangent planes to parameterized surfaces and surface area.
- Fire alarm scheduled in the NAC for 11am Thursday so we will need to leave the building then.
- Some exam 1 questions were regraded automatically so you may want to recheck your exam for updates.
- A few comments about Exam 1:
- The distance of an object to a plane is the distance from the closest point on that object to the plane. So in the case of a sphere, you can find the distance from the center of the sphere and then subtract the radius.
- A number of students had difficulty with differentiating arctan and using the chain rule. You may want to review 202 material.
- Read the questions and answer all parts of each question.
- If there is more than one place in a question with a parameter, you may want to use different letters for the parameters to avoid confusion.
- For two-variable limits, it is good to get in the habit of approaching the point in question (the origin) via curves with a parameterization using t to avoid confusion.
- A proof needs some words explaining what you are doing, just as we do in lecture and in the text.
- Exam 1 graded via Gradescope. You may need to sign up to see your exam if you have not used the system before, as indicated in the email sent.
- Exam 1 coming up, Thurs Sept 27.
- HW3 graded, scores on Blackboard. Make sure to answer the question that is being asked.
- No class Tues Sept 11 or Tues Sept 18 as campus is closed.
- The Webwork deadlines have been adjusted for the early homeworks to help students who were not able to sort out login problems.
- HW2 graded, scores on Blackboard.
- HW1 graded, scores on Blackboard.
Scale for written HW:
- Check plus = 4 pts = all the problems I looked at were good.
- Check = 3 pts = there was at least one thing missing or wrong
- Check minus = 2 pts = several mistakes or missing problems, needs review
- Dash = 1pt = something was turned in but there wasn't much correct work there
- If you are having difficulty logging in to Webwork:
- First, make sure you are using your CCNY identifier. If your ccny email address is bobama003@citymail.ccny.cuny.edu, then your identifier is "bobama003"
- Second, make sure can connect to your citymail account with your identifier and password.
- Citymail passwords need to be changed every six months or so. You may need to reset it at this CCNY link or by stopping by the helpdesk.
- Send me email if you are not able to succeed with the above steps, from your CCNY email account with your full name and CCNY identifier.
- We will be using the WebWork system for some homework.
- A welcome email has been sent the email address associated to CUNY First email addresses. If you are enrolled in the course and have not gotten a welcome email, make sure you are checking the correct account.
- Quiz 0 is posted on the Blackboard page and available in Blackboard and is due Friday, Sept. 14 but there is no need to wait. Sometimes Blackboard gets congested and unresponsive but do not expect any accommodation for one night of problems when the quiz has been available for multiple weeks.
- There are some available video lectures from former CCNY lecturer Dr. Marchese and CCNY instructor Jehvon Smith which may help with reviewing particular topics which are prerequisites for 203.
- The final exam will be a departmental final on Monday, Dec 18th, 1:00-3:15pm. The complete CCNY Fall final exam schedule is available at this CCNY registrar page
- Homework assignments usually due each Tuesday but the first one will be due Thurs Aug 30th.

Blackboard sometimes has some CUNY-wide problems which may made it difficult to take the online quizzes ("system error" and blank pages, for example.) So waiting until the last hour or even day to take the quizzes is a fundamentally bad idea.
