# MATH 115 - BUSINESS CALCULUS

Course Description

A survey of mathematical techniques used in the managerial, social and life sciences. Topics include systems of linear equations and matrices, linear programming, differential calculus, and applications of the derivative. Prerequisite: A grade of “C” or better in MATH-110 or MATH-105, or placement exam.

Textbook

Required Text: Brief Calculus: An Applied Approach, Eighth Edition, by Larson.
You will also need a calculator (scientific or graphing). Bring your textbook, calculator, pen or pencil, and paper to each class meeting.

Mission Statement

Benedictine University is dedicated to the education of undergraduate and graduate students from diverse ethnic, racial and religious backgrounds. As an academic community committed to liberal arts and professional education distinguished and guided by our Roman Catholic tradition and Benedictine heritage, we prepare our students for a lifetime as active, informed and responsible citizens and leaders in the world community.

Goals, Objectives, and Outcomes

Goals: Students will develop an appreciation for the basic concepts of differential and integral calculus and their applications to other areas, particularly in business and social science.
Common Student Learning Objectives:
Know and apply the central concepts of the subject matter.
Use technology to enhance learning.
Use inquiry and collaboration to solve problems.
Course-Based Student Learning Objectives: Upon completion of the course:
1. Students will become familiar with, be able to evaluate, and understand the significance and applications of mathematical functions, their limits, and their continuity.
2. Students will learn to evaluate derivatives, and to use them in various applications,
including those involving rates of change and optimization.
3. Students will be able to evaluate definite and indefinite integrals and to use them in solving problems.
4. Students will become familiar with exponential and logarithmic functions—their properties, limits, derivatives, integrals, and uses in modeling situations in business and social science.

Teaching Methodology

Lecture, discussion, demonstration, individual and group problem solving

Course Requirements

Attendance: A lot of material will be covered every week, so it is mandatory that you be present for the entirety of every class session. If, due to unavoidable circumstances, you have to miss part or all of a class, it is your responsibility to find out what you missed, learn the material covered, and make me aware of the reasons for your absence. my cell: 217-473-1783. If any class activities are missed due to an unexcused absence, the grade for that activity will be zero.

Due to the accelerated nature of the course, should you experience a medical condition which prevents you from attending any class(es), appropriate medical documentation must e provided immediately so it may be determined what, if any, accommodations are reasonable or possible.

Homework: A listing of the homework assigned for each testing unit will be distributed at the beginning of the unit. It will be turned in on the day of the test for that unit. When doing the homework assignments, you are allowed, and even encouraged, to work together, compare answers, or seek outside help, if this helps you in learning the material. You are not allowed, however, to merely copy someone else’s answers. This defeats the purposes of doing the homework: to give you practice and help you learn by doing, and to let me and you both know how well you understand.

In addition to handing in the assigned homework, you are also expected to read each section of the book as it is covered in class, and do as many additional exercises, other than those assigned to be turned in, as you need to for extra practice.

In class, there will be review quizzes, practice exercises, or individual or group problems.

Tests: There will be two unit tests, and a comprehensive final exam which focuses primarily on Chapters 4 and 5. The testing schedule listed in the course outline will be followed as closely as possible. Tests must be taken when scheduled. In case of emergency, other arrangements can be made, but you must contact me before or very soon after the test—do not wait until the following week. Otherwise, you get a score of 0 for the missed test.

Means of Evaluation

Homework: 15%; Quiz: 15%; Tests (including final exam): 70%
Grade: 90-100% = A; 80-89% = B; 70-79% = C; 60-69% = D; under 60% = F

FINAL EXAM

First Class Session:

Students should prepare for the first class session by looking over Chapter 0 in the textbook, paying particular attention to pages 0-2, 0-3, 0-13, 0-14, 0-15, 0-19, and 0-21. Also, since we will be covering the first three or four sections of Chapter 1 in the first class session, students may find it helpful to read over these sections before class begins.

Academic and professional environments require honesty and integrity, and these qualities are expected of every student at Springfield College-Benedictine University. In accordance with such expectations, academic integrity requires that you credit others for their ideas. Plagiarism, whether intentional or not, is a grievous offense. Any time you use words or ideas that are not your own, you must give credit to the author, whether or not you are quoting directly from that author. Failure to do so constitutes plagiarism.

Any incident of plagiarism and/or academic dishonesty may result in serious consequences. Penalties for academic dishonesty vary depending on the severity or extent of the problem but are always serious.

The following are consequences you may face for academic dishonesty:
• a failing grade or “zero” for the assignment;
• dismissal from and a failing grade for the course; or
• dismissal from the Institution.

Please refer to the Springfield College Benedictine University Catalog or the Student Handbook for a complete discussion of the Academic Integrity policy.

According to the Springfield College Catalog, grade appeals must be initiated 90 days prior to the end of one semester after the course in question has been completed. The process for appealing a grade is outlined below.

First, contact the Instructor.
1. A student must appeal to his/her instructor in writing (e-mail is acceptable) and provide specific reasons why his/her grade should be changed.
2. The instructor must respond to the student in writing (e-mail is acceptable) and provide a copy to the division chair.

Second, contact the Division Chair.
3. If the student wishes, he/she may then appeal to the division chair in writing (e-mail is acceptable) and provide specific reasons why his/her grade should be changed without the instructor’s permission. The student should understand that overwhelming evidence must be presented to the division chair to prove that the current grade is incorrect.
4. The division chair must respond to the student in writing (e-mail is acceptable) and provide a copy to the academic dean.

5. If the student wishes, he/she may appeal to the academic dean in writing (e-mail is acceptable) and provide specific reasons why his/her grade should be changed without the instructor’s or the division chair’s permission. The student should understand that overwhelming evidence must be presented to the academic dean to prove the grade is incorrect.
6. The academic dean must respond to the student in writing (e-mail is acceptable). The

Last day to drop with 100% refund = 1 week from beginning of class
Last day to withdraw with 25% refund = 2 weeks from beginning of class
Last day to withdraw from class = Beginning of the 8th week of class

Incomplete Request
To qualify for an “I” grade, a minimum of 75% of the course work must be completed with a passing grade, and a student must submit a completed Request for an Incomplete form to the Registrar’s Office. The form must be completed by both student and instructor, but it is the student’s responsibility (not the instructor’s) to initiate this process and obtain the necessary signatures.

Student Withdrawal Procedure
It is the student’s responsibility to officially withdraw from a course by completing the appropriate form, with appropriate signatures, and returning the completed form to the Advising Office. Please refer to the Student Handbook for important financial information related to withdrawals.
