Calculus for Business II                                                                                              Fall 2009–10

 

Scope of our course In this course we continue the study of calculus you began in Math 30.  Calculus for Business I is an absolute prerequisite for this course: You must have passed that course with a C- or better, and you must demonstrate that you understand the material. (This means Chapters 1 through 5 in our text, Applied Calculus, SCU edition, by Waner & Costable.)  On the second day of class you will demonstrate your understanding of some basic Math 30 skills on a short diagnostic test. 

 

If you have not already done so, familiarize yourself with the website for our book, www.appliedcalc.com . (Click through to the site for the 4th edition, on which the SCU edition is based.  Look for the tab that says “Everything for Calculus.”)  You can practice your skills in online tutorials and download Excel spreadsheets keyed to the text.  In Math 31, we will study Chapters 6 through 8, and also a chapter called Chapter P, which is about probability.

 

Course objectives  We connect calculus to the world of finance, economics, and other fields of business.  Your success will be measured by your ability to apply specific techniques to real-world problems.  These techniques include 1) finding antiderivatives,

2) evaluating definite integrals, 3) computing partial derivatives, 4) optimizing functions of several variables, with and without constraints, and 5) computing probabilities in situations that involve continuous random variables.  Specific applications include salary accumulation, consumers’ surplus, the Gini index, present value of future income, optimization of profit, minimization of costs, and risk analysis. You will also be asked to show mastery of various logical relationships among quantities, especially those at play in the Fundamental Theorem of Calculus.  All these areas bring together the three basic areas of mathematics:  analysis, algebra, and geometry; in our text, these appear as numerical, algebraic, and graphical points of view. 

 

Assessment  Graded examinations and non-graded surprise quizzes will test how well you meet these objectives.  On exams, especially the final, you will be asked to solve problems that are not exactly like ones you have seen before, showing your ability to apply your knowledge in novel situations.  Partial credit is given liberally for work that is partly correct, but in order to pass the class, you must do at least something entirely correctly.

 

My best advice is that you must think for yourself.  It is sometimes easy to let someone else solve a problem for you; that results in the problem being solved, but will be of no help to you when you are tested by another problem.  Please help others to help you by asking, “What’s wrong with my approach here?” or “Give me a hint,” rather than “What is the answer?”

 

Course requirements — the fine print — Required Reading!

Attendance and participation are required at every class meeting.  I ask you to be fully present, to behave professionally, and to stay for the whole period, except in special circumstances. No electronic devices are permitted in class.  You must ask questions when you do not understand.  This takes bravery, but your willingness to ask questions is vital to our course. Do not miss class on 11/20!

Homework (100 points) is due at almost every class meeting.  This is where you put your knowledge into action, solving problems for yourself.   See the homework rules and partial homework schedule below. Expect one short project using Excel.

Exams (100 points each) will be Wednesday, October 14 and Wednesday, November 18. According to department policy, exams can be taken only at these times. Bring a small (5 by 8.5 inches) blank blue book, available at the bookstore.  About a week before each exam, you will receive a set of Practice Problems to help you prepare; please do your best to solve these completely on your own.  On the first or second class period after each exam, there will be a short retest, where you will have another chance to demonstrate your command of the material.  The retests give you a chance to improve your score: the sum of the scores on your two retests (each out of 50 points) will replace your lowest exam score, if it is higher.  Everyone should take all the retests as a matter of course.  (Watch your calendar for possible retest dates!)

The final exam (200 points) will be Wednesday, December 9 at 1:30 PM in our regular classroom.  Bring a large (8.5 by 11 inches) blue book.   According to university policy, the exam must be taken at this time.  The exam will be comprehensive, and will test your technical facility, your skills with applied word problems, and your broad understanding of our course concepts.

 

Academic integrity: If you were to behave dishonestly, by cheating on an exam or by presenting the work of others as your own, that would be grounds for failing this course.  Please do your best to preserve my high opinion of your honesty.  Here is a detail worth mentioning:  You may work with others on homework or our computer projects, but the paper you turn in must reflect your own understanding and effort; I am particularly concerned that you think about the difference between working with a friend on homework, and copying from someone else. SCU policy appears at http://www.scu.edu/provost/policies/upload/Academic-Integrity-Protocol.pdf .

 

Calculators and computers:  Often it is helpful to use a machine of some kind for assistance with messy computations.  You are welcome to do this on your homework; for some problems it is quite necessary.  However, exam questions are designed to test your knowledge of concepts, rather than tax your ability to do arithmetic.  On exams, you will have to do arithmetic at the level of 60 x 70 = 4200, and calculators will not be allowed.

Advice on how to succeed in this course

 

There are many sources of help on campus.  Pi Mu Epsilon, the math honor society, staffs the Sussman room (O'Connor 31) with excellent tutors during posted daytime hours.  The Drahmann Center has individual tutors available and many drop-in hours.  But the most straightforward thing to do is to come and see me.  In most cases, I feel I am able to help more than one student at a time, so please announce your presence even if another student is in my office.  You do not need an appointment to come to regular office hours. If your inquiry is confidential, simply let me know.  It is impossible to schedule office hours that are convenient for everyone; it is your responsibility to arrange your schedule so that you can attend at least some of the posted office hours each week.  Don’t be afraid to ask for an appointment outside of posted hours.

 

Contact me:    O'Connor 314, 554-4430, http://math.scu.edu/~ffarris, ffarris@scu.edu

Office hours:  MWF 12:30–1:30, Tu 1:15–2:15 PM, and by appointment.  Memorize these!

 

To request academic accommodations for a disability, students must contact Disabilities Resources located on the second floor of Benson.  Phone numbers: (408) 554-4111; TTY (408)554-5445.  Students must register and provide documentation of a disability to Disabilities Resources prior to receiving academic accommodations.

 

Homework Schedule through Exam I

Each assignment consists of three types of problems:  R problems are required, but will not be graded by our homework grader; all are odd-numbered problems with answers in the back of the text; do these first as a warm-up.  G problems are to be graded; they are the only ones you are to turn in; most are even-numbered problems.  E problems are suggested for extra practice.

 

For G problems, consider any part marked in the text with a T for technology as optional, unless the computations can be done with a calculator.  Do not turn in any computer-generated tables or graphs. When turning in G problems please fold your paper in half vertically, write your name and the date on the outside and staple multiple sheets together.  Our homework grader gives full credit only when you present correct work with reasonable written explanations of your process.  Partial credit is given for effort beyond simply copying the problem.  Note: When hwk is due right before an exam (the practice problems), keep a copy to use in class.

 

The date given is the date the homework is due (at the beginning of class).  Remember to keep a note containing the particulars of any homework problem you wish to ask about in class.  I reserve the right to over-ride this schedule if necessary, so be sure to listen in class for announcements.  The assignments due 10/9 and 10/12 are on the long side, so please plan ahead.
