| HomeMath 132, Spring 2012
Monday, May 14 Grades are posted, and the semester is done. I wish you the best of luck with all your future courses. Thursday, May 3The answers for the multiple choice/long answer blends on the Spring 2010 final are: 1. iv, iii; 2. i, iv; 3. ii; 6. i, iii, ii; 7. ii, v. Monday, April 30As far as old exams go: the exams for Math 132 in Spring 2010 were mainly hand-graded. We've done things in enough of a different order that the midterms from that semester would not have been useful for you, but the Spring 2010 final may be of some help in your studying. (I expect this to go up on the oldexams page soon, also.) Friday, April 27Also, here are the quiz and worksheet from Tuesday. Friday, April 27 My office hours for reading week are: M 4pm - 5pm, T and W 10am - 12pm, Th 11am - 2pm. Monday, April 23 Webwork problem 4 had at least two problems with it. I think all the bugs should be out now. Wednesday, April 18The solutions to Quiz 5 are available. Tuesday, April 17 Worksheet 12 is available. Friday, April 13Quiz 4 solutions, as promised. Friday, April 13 The webwork due date was incorrectly set -- sorry about that. Now fixed so that hw 12 is open, and will be due this coming Wednesday. Friday, April 13Quiz 4, given today, is available. (Solutions to follow.) Tuesday, April 10 As you've all seen by email: Saturday, April 7Homework hint On #15, the hard part is finding the limit of f_{i+1} / f_{i}. Assume that limit L exists, and by expanding the recursion (recalling that f_{i+1} = f_{i} + f_{i-1}), set up an equation involving L. Solve! Friday, April 6The midterm grades now on WebSTAC are based purely on the grades from your first two exams, and do not include WebWork or quiz grades. Thursday, April 5Draft Exam 3 solutions are now posted. Please note that, in order to get these up as quickly as possible (before the course withdrawal deadline), I have not proofread them as closely as I usually would. Thursday, April 5Exam 3 is now posted. Solutions will follow as soon as we can. Wednesday, April 4I'll be in my office 1-3pm today to help you with any last-minute questions. My usual office hour on Thursday will be cancelled. Tuesday, April 3Worksheet 10 is now available. Good luck studying for the exam! Monday, April 2I've posted a sheet which carefully states the Domination/Direct Comparison test at vertical asymptotes. Wednesday, March 28 A short WebWork is posted, to help you practice the newest material for the exam. (Due Wednesday). Tuesday, March 27 Somewhat belatedly: here are solutions for exam 2. Monday, March 26 I've turned off the submission limit on #3. Please try to do it in as few submissions as possible, and generally to understand the problem. Friday, March 23 Hints on WS 8 # 1d:This problem hinges on showing that the integral e.g. from 1 to 2 diverges. There are two basic approaches: Tuesday, March 20The worksheet from today is available for download. Friday, March 16 I hope everyone is having a relaxing and refreshing break. Wednesday, March 7 Here is the Worksheet from yesterday's section. Tuesday, March 6A pdf of Exam 2 is available. Solutions will appear later. Monday, March 5 Good luck on the exam tonight!! Exam seat lookup here. Saturday, March 3Ryan has written up some brief informal solutions to selected problems from Worksheets 5 and 6. Friday, March 2The new webwork is posted. Problems 1-12 are highly relevant to Monday's exam, and I highly recommend doing these problems over the weekend. Thursday, March 1Also, Worksheet 6 is now available for download. Thursday, March 1 The differential equation for the propofol problem (Michael Jackson problem) on the worksheet is y' = K - (ln 2)/45 y. Monday, February 27 The purpose of the salt/water problems on the WebWork is to give you some experience in setting up differential equations, the modeling that we spent time on last week. You should set y to be the mass of salt in the tank. Friday, February 24Solutions for Quiz 2 are now posted. Friday, February 24Here's the quiz from lecture today. Friday, February 24The promised review sheet on exponential and log functions is now available, as is Worksheet 5 from section. Tuesday, February 21Note that bar(x) = M_{y} / M. (The formulas for the center of mass in class were correct, but M_{x} and M_{y} are backwards from what it seems they should be, and this matters for some of the webwork problems.) Sunday, February 19For the webwork, please note that the centroid of a shape is the center of mass of that shape with uniform mass density. (See p395 of your textbook for additional discussion.) Friday, February 17 1. As promised, Exam 1 solutions are available. Thursday, February 16 Webwork 5 is now posted. Wednesday, February 15Here is Worksheet 4, with the error in 3a fixed (should be "points where slope is plus or minus 1", was "where slope is 1"). Tuesday, February 14 1. Physical exams are in the Math 132 cubbyholes, which are between room 112 and room 114 in Cupples I Hall. The sheets are sorted by the problem number, and it would be courteous to your fellow students to keep them that way. Tuesday, February 14 Happy Valentines day!! To celebrate, some homework hints: Wednesday, February 8 Good luck on the exam tonight!! Exam seat lookup here. Monday, February 6 A mockup (link now fixed) of the exam format is available. The real exam will have 5-6 multiple choice, plus 4 long answer (each with multiple parts). Tuesday, January 31The worksheet from today is now posted. Please note that 2b had an error in the hint -- the useful example to look at is Example 7 from 5.5 (rather than from 5.4). Tuesday, January 31 As announced in lecture, my Thursday office hours will be cancelled. Sunday, January 29A list of basic integrals is now posted. Thursday, January 26The webwork due next week is posted! Tuesday, January 24On problem 14 of the webwork, you want the total distance traveled, and not the displacement ("net" distance traveled). That means you'll have to split up the interval by where v is positive and v is negative, and take definite integrals with appropriate sign. (See e.g. Example 5 of Section 5.4.) Tuesday, January 24Here is Worksheet 1 from today's recitation section, including Problem 3d. Thursday, January 19 The first webwork problem set is posted. Please click on the webwork link to the left. Tuesday, January 17 Welcome to Math 132! The Syllabus and Schedule are linked at the left. Last modified May 14, 2012 |
