MATH 142B (Winter 2019)

Welcome (back) to MATH 142! This is the page I'll be using for posting things such as contact information, office, hours, section details/announcements, review session times, study guides, etc.

• Name: Vaki Nikitopoulos
• Email: enikitop@ucsd.edu (Please include [MATH 142B] in the subject of your emails.)
• Section: 957509 A02, Wednesday 7:00PM-7:50PM, AP&M 5402
• Office Hours: Thursdays 8:20AM-9:20AM (AP&M 5412 with backup room 5402) and Fridays 11AM-12PM (AP&M 5412 with backup room 7421 on Weeks 2, 5, 6, 9, and 10)

Announcement (01/10/19): My Friday (01/11/19) office hour will not be happening this week because I have a previously scheduled meeting just this week. But, starting next week, I'll have both office hours.

Announcement (01/14/19): I have obtained rooms for most of my office hours. The plan is as follows:

1. Every office hour, we shall start in my office (AP&M 5412). My desk is to the left, all the way back, and to the right. I have a piece of paper that says "Vaki" pinned up.
2. If things get too crowded, then we'll move to the backup room. Please see the above bold print (office hours bullet point) for the backup rooms. So if I am not at my office, then check the backup room listed for that day/week. I shall also try to write on the board next to my desk if we moved to the back room.
3. You'll notice that not every office hour has a backup room. If things get too crowded on a day on which I do not have a backup room, then I shall request one for that time from the front desk. I'll post it on this website and write it on the board by my desk.

Announcement (02/04/19): I uploaded a study guide for the first midterm. (Find it above.) I constructed it by adding onto the one I made for the first quarter, so it has all of that material as well. This material that is new this quarter is contained in Sections 6, 7, and 8. Please let me know if you find typos, and please also add your own examples and extra results from the homework. These can be just as important as the stuff I wrote!

Announcement (02/05/19): I'm going to have an extra office hour (8-9PM) after section tomorrow (Wednesday, 02/06/19) in the same room (AP&M 5402). Please bring any questions you might have about exam review, old homework problems, quiz solutions, etc.

Announcement (02/22/19): I screwed up a sign in office hours today. It was pointed out to me right after. I had written that

F(x_0 - h) - F(x_0) = integral from x_0 - h to x_0 of f(t) dt.

This is incorrect. The thing I should have written, which gets rid of the sign problem I was experiencing, is

F(x_0 - h) - F(x_0) = - integral from x_0 - h to x_0 of f(t) dt.

Note the minus sign. If you have problems, then shoot me an email.

Announcement (03/07/19): I apologize for the late notice, but my Friday (March 8) office hours are going to be cut 15 minutes short. If we don't get through everyone's questions tomorrow, then please email me, and I will help you out if you need it.

Announcement (03/10/19): I updated the study guide through Fourier Series. Please take a look, and tell me if you see any typos. Also, it is very important that you incorporate some results from your homework. That will really complete the study guide. I hope this helps you guys study more efficiently! Finally, email me if there are topics that confuse you particularly badly that you would like me to give tips about for the final when I do my review session.

Announcement (03/17/19): I updated the study guide for the last time (modulo if I notice typos). I added a section about the analysis on $\R^n$. Please take a look, and tell me if you see any typos. Once again, please add your own examples and things from the homework. (I looked through the homeworks, and I would say some useful results are contained in problems 4.2, 4.3, 5.1, 5.2, 5.3, 8.1, 8.2, 8.3, 8.5, and 8.6. So it would be good to review those if you have time and to have the results in the back of your mind.) Good luck, everyone! Let me know if you have questions, and come to my extra office hour if you need last-minute questions answered. And again, FILL OUT EVALUATIONS FOR ME!
