# Math 1a: Section 2: Multivariable Calculus

## UC Berkeley, Fall 2011

Announcements:

• (12/18) Grades are submitted. You should be able to see them by Monday night, 12/19. Final exams can be viewed next semester (I think not in the first couple of weeks) in 970 Evans. Have a nice break!
• (12/7) DSP students needing extra time on the final: Please email me so that I can arrange the details with you. Please also let me know if you have any other exams or schedule constraints on 12/16.
• (12/7) I will have office hours on Thursday 12/8 from 1:00 to 3:00. I will also have office hours on Wednesday 12/14 from 2:00 to 5:00.
• (11/21) Here is the score distribution and curve for the second midterm.
• (11/8) DSP students will take the midterm in room 959 Evans.
• (11/8) I will have office hours on 11/10 from 12:30-3:00.
• (10/25) The definition of concave and convex functions on page 290 is also wrong for nondifferentiable functions. (It is fine for piecewise differentiable functions.) I gave a correct definition in class.
• (10/25) On page 272 of the book, near the top, it says "This absolute maximum is not a local maximum because it occurs at an endpoint." This is wrong (assuming we are regarding the domain of the function as the closed interval). Sorry. "x is a local maximum of f" means "f(x) >= f(y) for all y sufficiently close to x (and of course in the domain of the function)". In particular an absolute maximum is always a local maximum. At least, that's standard mathematical terminology as I understand it. If on an exam there is ever a situation like this where what the book says conflicts with standard mathematical terminology, I will be sure to clarify.
• (10/25) My office hours will continue to start at 1:30 until further notice. Currently there is more than enough time in office hours to answer all questions, but if that changes I will reschedule.
• (10/12) Office hours on 10/13 will be delayed until around 1:30.
• (10/10) The score distribution and curve for the first midterm is here.
• (10/3) DSP students: for the midterm, please go to my office, 923 Evans, at 3:30 on 10/4. One of you (whom I talked to about this) will take the exam in my office; the rest of you will take the exam in 947 Evans.
• (9/30) My office hours next week will be on Tuesday 10/4 from 12:30-3:00m instead of Thursday, so that you can ask me last minute questions before the midterm.
• (9/30) If you are in the DSP, I am still waiting to find out where you will take the midterm. Meanwhile, if I don't already have your email address, please email me so that I can contact you once I have a room.
• (9/28) Alvin Kerber will hold a midterm review session on Sunday October 2 from 1-4pm in 166 Barrows Hall. Students from all discussion sections are welcome to drop in for all or part of this time.
• (9/13) The GSI's whose webpages are linked below have office hours which you can attend if you are unable to attend your own GSI's office hours. These webpages also have some useful practice materials and calculus links whicn you should check out.
• (8/25) If you are a representative of an organization wishing to make announcement in my class: Sorry, my policy is not to allow advertisements of any kind, no matter how worthy the cause.
• (8/25) Please note that students must attend the discussion section that they are registered for. If you want to change discussion sections, you can switch yourself on TeleBears to any other section with available space. Currently most sections are full, but spaces should open up as other students switch sections or drop the class early in the semester. I apologize for the inconvenience. If you cannot find a section that fits your schedule, or if you have other questions about enrollment, please see Barbara Peavy in 967 Evans.

Instructor: Michael Hutchings. Tentative office hours (starting 9/1): Thursdays 12:30 PM to 3:00 PM, in room 923 Evans. Office hours may occasionally be rescheduled, so you might want to check the announcements above before going. If you have questions outside of office hours, you can send me an email at [my last name with the last letter deleted]@math.berkeley.edu.

Lectures: TuTh, 3:40-5:00, 2050 Valley LSB.

Discussion sections: For the current schedule of discussion sections see schedule.berkeley.edu. The GSI's are:

Textbook: James Stewart, Single Variable Calculus, Early Transcendentals for UC Berkeley. This is a custom edition, which consists of selected chapters from Calculus: early transcendentals, sixth edition. It is used for both Math 1a and Math 1b. If you can find an inexpensive copy of the full book, you can use that instead. Beware that the Stewart calculus line contains many different products and editions. Different versions of the book may present the material in a diferent order and will probably not have the same exercises.
