Announcements
12/19/08: Final grades are up on tritonlink. If you're contacting me over the next few weeks, please note - I am not in San Diego, and will not be until the 11th of January. Have a great break, and best of luck in any future math classes!
12/12/08: Hi, all. It's taking us a bit longer than expected to get everything finalized so if you've been contacting me, I promise I'll get back to you once I know the answers.
12/9/08: Hi all, exams are a bit more than half graded now and I hope to finish up tonight into tomorrow. (Then I have to assign grades, etc. Everything will be done by the end of the week, certainly.) Final grades will be posted on Tritonlink after that. If you want to know how you did on your final, email me or John around the end of the week (Thursday/Friday-ish.) If you want to see your final, I will have them at the beginning of next quarter so contact me then. I will be in a different office, and gone for the first week or so of the quarter, so email me first.

Overall, the final was tough, and you guys are doing pretty well all things considered. Just a quick note: When you are asked to verify that something is a solution to a Diff-Eq, you don't need to *solve* it; just compute the necessary derivatives and plut it in. For verifying dP/dt = P(1-P) has soln 1/(1+e^{-t)), it's not at all necessary to solve it. This is causing most of you all kinds of trouble. Have a good winter break, and I hope you enjoyed the class!
12/7/08: Last day exam notes:

12/4/08: I revised the practice exam to fix a few bugs it had. Don't forget: old practice exams are a great study guide too!
12/3/08: As announced in lecture: Today from 11-1 John has extra office hours. Also, I have extra office hours Saturday from 12-2.
12/1/08: A practice final is now available.
12/1/08: Don't worry about drawing the slopefield in 11.5.4(b). Note that identifying stable/unstable asymptotes is important, though - and it's good to know how to sketch solutions to differential eqns, but we haven't talked about drawing full slope fields, and I won't put that on the exam.
11/24/08: Okay, here are the rules for the corrections:
11/23/08: The average on the exam was a 64. Good job, really! We'll discuss the corrections tomorrow. What I'm inclined to do is the following: you can get up to half credit on what you missed, with the caveat that the highest you can raise your grade to is an 89. Also, we will be harsher when regrading so make sure you write your new solutions completely and clearly! Also, HW 9 is posted (due a week from Friday, last day of class.) See you tomorrow morning.
11/19/08: Hi all, I'm grading your exams now. Before you freak out too much: yes, it was a bit long. Still, you guys are doing well considering, and I want to reward your hard work. So, what to do? I have a good idea, I think, but we'll talk about it Friday after I know exactly how you did.
11/19/08: Homework 8 is due MONDAY 10/24 by noon, insted of Friday. I figured you could use a little break.
11/17/08: Reminders:
The second midterm is Wednesday. You are allowed a sheet of notes, and a calculator as before. Note that you don't need to copy the entire table of integrals from the back of the book, if I ask for anything really bizarre I will provide the formula. However, I expect you to know, eg. the anti derivatives of sin(x), cos(x), sec^2(x), x^n, 1/x, etc, etc - the basic ones that we use a lot.

On the first practice midterm, 2b, I totally messed it up. It should not go from 0 to 5. Just be able to do it as an indefinite integral and realize why it's wrong as written. (By the way, if you take the upper bound to be sqrt(5), then the integral is improper and diverges - try and show that, it's good practice.)

I have extra office hours tomorrow (Tuesday) 10-12. Please feel free to drop by, I'd be happy to answer questions. Good luck with your studying, see you Wednesday!

10/13/08: A second practice exam is available here . Good luck with your studying!
11/12/08: Here is a practice exam 2 that I wrote. Note that even though they are not covered on the practice, 8.1, 8.6, etc. are still fair game. We did not (and will not) cover arc length in 8.2, so there will be no arc length on the exam.
11/10/08: I get the impression that some people are confused on the material we just covered today (especially in finding volume by slicing.) I will touch (briefly) on it again as it's intimately related to 8.2 which we are doing now. If you want some additional examples, Prof Al Shenk has some written some additional examples which are here.
11/10/08: Some information on the exam:
The second exam is next Wednesday 11/19/08 during lecture. You will be allowed one 8.5x11 sheet of notes. I will, soon, write up a sample exam. Here is a sample exam from a previous 10B class.
11/10/08: REMINDER: Tomorrow is Veteran's Day, and there is no section.
10/30/08: I've posted the next few homeworks, through HW 8. I put a few extra 7.4 problems on the next homework so you can get some more practice with these techniques.
10/30/08: One of the problems, 7.4.45, has a last step that we haven't talked about how to do and none of the examples in the section address. You may leave the answer as - csc(arctan(t)) which is correct, but I will show you how to get the books answer during the first part of lecture tomorrow.
10/23/08: A few announcements:
I won't have the tests back tomorrow (they will be handed out in section) but John or I may have grades available tomorrow. (I do not now). If you are really super worried in a 'I'm not sure if should I drop the class?' kind of way, please get in touch with us. John has the exams, so maybe you should get in touch with him first.

I graded two of the midterm problems (the integrals, and the initial value problem/2nd FTC problem) and was quite pleased with how you did, by and large. If you have comments on the exam I'd enjoy hearing from you. If you have questions about the exam, I'd enjoy hearing those too - or ask John in section. I don't have office hours officially tomorrow, but will hang out in my office for a bit after class if you've got questions.

I will be away on Thursday 11/6 during my office hours. I will move them to Friday 11/7 after class (9-10) for that day only.

10/16/08: Here is a second practice exam. I think the difficulty is more reasonable. Monday's class is a review: feel free to ask about either of the practice exams then or in section Tuesday.
10/15/08: Here is a practice exam. I think it is challenging.
10/14/08: Some information on the exam:
The first exam is next Wednesday 10/22/08 during lecture. You will be allowed one 8.5x11 sheet of notes. I will, soon, write up a sample exam. Here is a sample exam from a previous 10B class. No guarantee that my exam will be similar, but it should give you at least an initial idea. The next sample exam I post I will have written, so it will give you a better idea of what questions I like to ask.
10/14/08: Homeworks 4&5 have been posted. I split the assignment for 7.2 between the two assignments, because I didn't want you to have too much you had to get done next week with the exam and all, but 7.2 (integration by parts) is fair game for an exam question since we're covering it on Friday. (So you might look over the other questions if you have time).
9/25/08: Welcome to the class. I will try and post announcements here. I wrote a little review of some of 10A's material in case you've forgotten. (UPDATE: I've even uploaded it now!) 10B really builds on 10A, so hopefully it is of use. The first 3 homeworks have been posted.

Looking for additional help?
A tutoring lab for Calculus students will be open 10 to 12 hours daily Monday through Friday in APM B402. There will usually be at least 2 tutors and/or TAs available to help with homework, calculators, and coursework. Take a look at the schedule to see when it is open or when your favorite tutor or TA is there. We strongly recommend that you make use of the Calculus Tutoring Lab.
