Alllocations have limited seating, the proctors will have a limited number of exams at each location,and if your exam gets mixed in with a different section, your exam grade may not be recorded.You must bring your Stony Brook ID card to the exam.(2) Please show up no later than 8:25pm. The exam will begin at 8:30pm and you will not receiveextra time if you show up after 8:25pm.(3) Please take every other seat starting with the front row. Once a row fills up, please take aseat directly behind another person (not diagonally from another person). You can put your bagand/or jacket on one of the seats next to you in the same row.(4) Blank paper will be provided, in addition to an exam booklet (4 sheets stapled together). Theexam booklet should have sufficient space for solutions, but you can staple additional pages to it asneeded. If you do so, please write your name and ID number on each additional sheet and indicatein the exam booklet where to find your solution. Any scrap paper that you not want to be gradedshould not be handed in (except separately from the exams, for recycling).(5) No notes, books, calculators, or cell phones may be used during the exam. Please bring pen-cils/pens and an eraser. The only items that may be on your desk are pencils/pens, an eraser, yourexam booklet, and the scrap paper provided by the proctors.(6) When you receive the exam, please do not open it until the proctors say it is time to start.However, please do fill in your name and Stony Brook ID number and circle your section numberon the front cover of the exam. The exact front cover of the exam is at the end of this handout.(7) All problems on the exam should be stated unambiguously. If you feel there is an issue with astatement of a particular problem, please let a proctor know; however, the proctor will not confirmwhether your interpretation of the problem is correct.(8) Out of fairness to others, please do not open your exam booklet ahead of time and stop workingwhen the time is over. Your exam score will be reduced by 5 points per minute of either violation.(9) When you are finished with the exam or when the time is called (whichever comes first), pleasetake it to the front along with your Stony Brook ID card. Put the exam in the pile for your sectionand sign the photo roster under your picture immediately after.(10) You can leave before the time is over, but please do so as quietly as possible and close thedoor very gently.Before Midterm INote that PS5 is due two days earlier than usual (except in L01). This will make it possible topost solutions to PS5 before noon on Wednesday, 10/07.The midterm will cover Sections 7.1-7.5 from the textbook and the Notes on Second-Order LinearDifferential Equations. You should re-read these sections thoroughly, review Course Summary I,and study the solutions to PS1-5 (even if you did all/most problems correctly). Make sure youcan do all problem set exercises from the above six sections and some other related problems fromthe textbook and the notes, especially from pp551-552 (these do not cover second-order differentialequations though).The first midterms from Fall 05 and Spring 06 are available on the course website, along withsolutions. Please try doing these midterms in 90 minutes (each) before looking at the solutions. Ifyou do not do well on them, this should be a serious wake-up call for you. The first midterm inthis class will be similar in many aspects to these midterms (especially the one from Spring 06),though there will be some differences and your midterm will be slightly harder overall than themidterm from Spring 06. While the Fall 05 midterm contains a mixing problem (which will notappear on your exam), instead of an Euler’s method problem (which will appear on your exam),you should still be able to do the Fall 05 midterm.A lot of you have at least a rough idea as to what has been happening in the course, but someof you have difficulty implementing this in practice. As it is the latter which is important (andevaluated on the exams), it is essential to be able to the textbook problems correctly. The onlyway to do this is to try to do as many of them as possible and at the very least make every effortto do the assigned exercises.If you have any questions, please come to office hours (lots of them on Wednesdays!), MLC, and/ora Residential Tutoring Center. If you do not do well on the first midterm, it will be harder to doreasonably later.After Midterm IDetailed solutions to the midterm will be available on the course website on Thursday morning;please print these out before the following lecture. If the solutions do not satisfactorily explainhow your solution to a particular problem was graded, please check with the primary grader forthe given problem (the primary graders for all problems will be listed on the website). If your totalexam score was incorrectly tallied, please let your instructor know.If you do not do sufficiently well on the first midterm, you should quickly consider your choices:(1) drop down to MAT 126. This might be the best option, especially if you have not yet receivedcredit for MAT 126. If you have received credit for MAT 126, you will not receive credit again,but you might be more prepared to take MAT 127 in the spring.(2) drop down to MAT 132. This is a risky option, but might be better in the long run if itworks out. MAT 132 moves faster than MAT 127, but starts earlier. So you’d see most ofSection 7 again, but then MAT 132 will fly quickly through Section 8.(3) withdraw from MAT 127. You’d receive a W on your transcript.(4) put much more effort into MAT 127 in order to do much better on the second midterm andthe final. Depending on how poorly you do the midterm, your schedule outside of MAT 127,and your priorities, this may not necessarily be a realistic option.The deadline for (1) and (2) is Friday, October 23, and for (3) is Monday, November 2, but youmight be better off not procrastinating. The second midterm is on November 4 and so is too lateto help with your decision. Of course, it would be best to avoid getting faced with one of thesechoices in the first place, so try to get ready for the first midterm as much as possible.If you have any questions, please
