Math 105, 2010W Term 2
Integral Calculus with Applications to Commerce and Social Sciences
This is the common page for all sections of MATH 105 in Term 2 of the 2010W session (January to April 2011). Here you will find the course outline, suggested homework and practice problems, course policies, exam dates, common handouts and supplementary notes, other course information, and information on available resources. For section-specific information, please follow the individual section links below or contact your instructor.
The required textbook for this course is Calculus: Early Transcendentals, 1st edition by Briggs and Cochran. This is the same textbook as used in Math 104 and is available at the UBC Bookstore. It has a new edition this year, so there will not be used copies around. The bundle comes with access to some online resources that include a study guide and student solutions manual. Some additional course material may be provided as needed.
Beginning-of-term registration information
- At last report, all sections of Math 105 were full.
- If you are not registered in a section, please do not attend it without the instructor's approval.
- Instructors do not have the authority to "fit you in". Such requests have to be processed by the math department office (Room 121 Mathematics Building).
- Math 101 and Math 103 are accepted in lieu of Math 105 as prerequisites by all faculties. You may want to check for available spots in these courses.
- The math department is conducting registration help sessions in January.
- If you need to switch from one section to another, the best way this can be done (with the sections full as they are) is to find somebody in the other section who is willing to switch with you. Then come with that person to either the main office (Room 121) or to a math department registration session.
Your grade will be computed based on the following formula:
Please note that grades may be scaled to ensure fairness across sections. The lowest 2 homework marks will be dropped from your grade calculation.
- Final Exam 50%
- 2 midterms 15% + 15% = 30%
- Course-common hand-in homework 15%
- Other section-specific coursework (to be decided by your instructor) 5%
Exam Dates and Policies
- The final examination date for this course (to be held in April) has not yet been announced. Please do not make end-of-term travel plans before this date has been released.
- There will be two midterms in MATH 105. The dates are:
- Midterm 1:
- Thursday, February 3 for T-Th classes.
- Friday, February 4 for M-W-F classes.
- Midterm 2:
- Thursday, March 17 for T-Th classes.
- Friday March 18 for M-W-F classes.
- The final exam will be common to all sections of MATH 105, and will account for 50% of a student's final grade. The remaining 50% will be based on term work. The final exam generally will not be weighted higher for students who perform better on this test than they did during the term, although some allowance may be made for students who perform significantly better (an increase of 30% or more over their term mark). Such decisions are based on the sole discretion of the instructor.
- The final exam is board marked (i.e. all instructors teaching this course mark the exams together) to ensure consistency and fairness across sections.
- Grade calculation: The mark distribution of the term work of each section may be scaled based on the final exam mark distribution of that section. These adjusted term marks will then be used to compute a student's final grade. Any scaling is performed to ensure fairness in the final grades across sections. It is not expected that such scalings would result in significant grade changes.
- Exam aids: No unauthorized electronic devices will be allowed in the midterms or in the final exam. This includes calculators, cell phones, music players and all communication devices. Students should not bring their own formula sheets or other memory aids. Common formula sheets may be provided to all students depending on the material covered, in which case the content of the formula sheet will be disclosed in class prior to the exam.
- Missing midterms: If a student misses a midterm, that student shall provide a documented excuse or a mark of zero will be entered for that midterm. Examples of valid excuses are an illness which has been documented by a physician and Student Health Services, or an absence to play a varsity sport (your coach will provide you with a letter). There will be no make-up midterms, and the weight of the missed midterm will be transferred to the final examination. Please note that a student may NOT have 100% of their assessment based on the final examination. A student who has not completed a substantial portion of the term work normally shall not be admitted to the final examination.
- Missing the Final Exam: You will need to present your situation to the Dean's Office of your Faculty to be considered for a deferred exam. See the Calendar for detailed regulations . Your performance in a course up to the exam is taken into consideration in granting a deferred exam status (for instance, failing badly normally means you will not be granted a deferred exam). For deferred exams in mathematics, students generally sit the next available exam for the course they are taking, which could be several months after the original exam was scheduled.
- Please bring your student ID-s to both midterms and the final.
- About 2-4 problems will be posted on this website as homework problems every week and collected the following week. These problems will be graded by a marker assigned to this course. The grade you receive from turned-in homework will constitute 15% of your total grade.
- The worst 2 of your homework grades will be dropped. This includes the homework that you do not turn in, which will automatically be assigned a grade of 0.
- The work that accounts for the remaining 5% of your coursework grade will be decided by your instructor and may vary from one section to another. This is based on various factors such as lecture times, class size etc.
- In addition to the homework problems, a list of suggested practice problems will appear on this website every week. These are not to be turned in and will not be graded. It is however strongly recommended that you work through these problem sets as they are based on the syllabus for this course, and therefore omit problems that may be in the text but are unrelated to the course material. They also accurately reflect in terms of content and level of difficulty the problems you will encounter in quizzes (where applicable), midterms and the final.
- Late Assignments: Depending on the lecture schedule, your section instructor will inform you of the time by which homework should be turned in so as not to be deemed late. Late assignments are not normally accepted for marking and will receive a grade of 0.
- UBC takes cheating incidents very seriously. After due investigation, students found guilty of cheating on tests and examinations are usually given a final grade of 0 in the course and suspended from UBC for one year. More information.
- Note that academic misconduct includes misrepresenting a medical excuse or other personal situation for the purposes of postponing an examination or quiz or otherwise obtaining an academic concession.

- MyMathLab is an online resource that is part of the textbook package. It has a rich database of problems of varying levels and provides guided help and feedback. In order to access MyMathLab, you will need to login here with the course ID pramanik71956.
- First year can be an overwhelming experience for many students. If you find yourself having serious academic difficulties in this course, it is best to talk to your instructor as soon as you can.
- The course is divided into two parts. Roughly speaking, we will cover the theory of integration (Chapters 5 and 7) before the first midterm, and differentiation of functions of several variables (Chapter 12) by the second midterm. The rest of the time will be devoted to discussing applications of the techniques learned above in business, economics and social sciences. This will include some material from Chapter 6 and some additional notes on random variables.

Midterm and exams
Midterm 1 study material
- Studying for the first midterm? Here is the link to the math department's archive of past exams. Note that not all the earlier versions of Math 105 followed the same textbooks or covered the same material, or covered the common topics in the same order as we are doing now. On the other hand, Math 101 and Math 103 in spite of being different courses, have quite a large overlap with Math 105 in terms of course content.
Here is a list of problems from the past exams that covers the syllabus of the first midterm, and that should help you prepare for the test.
- Here is a sample midterm 1 with solutions .
- Here you can find another practice midterm with solutions.
- This formula sheet will be provided to all students during the first midterm. Do not bring your own!
Midterm 2 study material
- If you are preparing for the second midterm, here is a list of practice problems from past math exams. Note that not all of the midterm material is adequately represented in this problem set. See also the sample midterms below.
- Sample midterm 1 with solutions.
