Course Title and Description: (CREDIT 3.0) Business Mathematics II. Derivatives, curve sketching and optimization, techniques of derivatives, logarithms and exponential functions with applications, integrals, techniques and applications of integrals,
multivariate calculus.
Prerequisites: High school algebra I and II and geometry or satisfactory performance on a qualifying examination. Credit
will not be given for more than one of MATH 131, 142, 147, 151 and 171. Note: A tentative schedule for this course, including
the topics to be taught, is attached to this syllabus.
Calculators Policy: The TI-83, TI-83 Plus, or TI-84 graphing calculator is required for this course. Use of any other calculator is not allowed, and the use of other calculators will not be discussed in class. Sharing calculators during quizzes and
exams is strictly forbidden and is considered an act of scholastic dishonesty. The only programs you will be allowed to have
on your calculator are those (if any) that I give you in class. All other programs must be erased from your calculator with no
exceptions.
Email Policy: Check your neo email account EVERY day. You are responsible for any information I send via email. If
you send an email to me, be sure to include your full name and course number (142) in any email. If any of this information is
missing, it will delay my response. Note: Because of privacy rights, I cannot discuss grades via email or over the phone.
Cell Phone Policy: As a courtesy to me and your classmates, all cell phones must be OFF and put away during lecture.
Grading Policy:

Note: Any questions regarding grading/scoring must be made within two business days of the return of the exam or quiz or no
change in the grade will be made.
Make-up Policy (apply to all exams, quizzes and graded homework): No make-ups will be given without written evidence
of an official University excused absence. (See University Student Rules.) According to Section 7.3 of the University Student
Rules, for an absence to be considered excused, the student must notify his or her instructor in writing (acknowledged e-mail
message is acceptable) prior to the date of absence if such notification is feasible. In cases where advance notification is not
feasible (e.g. accident or emergency) the student must provide notification by the end of the second working day after the
absence. This notification should include an explanation of why notice could not be sent prior to the class. If no such notice is
given, the rights to a make-up are forfeited. In addition (and also in accordance with University Student Rules), a written excuse
must be presented upon return to class. Specifically, in the case of illness or injury, students are required to obtain a confirmation note from a health care professional affirming date and time of a medical office visit regarding the illness or injury. I will
NOT accept the Explanatory Statement for Absence from Class form as sufficient written documentation of an excused absence.
Exams: There will be three in-class exams and a comprehensive final, tentatively scheduled as shown below. I will NOT

curve test grades.
Tentative Exam Schedule:
Exam I: July 18
Exam II: July 30
Exam III: August 8
Final Exam:
Tuesday, August 13, 1pm-3pm
Quizzes: Announced and unannounced in-class or take-home quizzes will be given throughout the semester during class. Each
quiz will be graded on a 10-point scale. One lowest score will be dropped before calculating your combined quiz average.
Graded Homework: Graded homework assignments will be completed online using your WebAssign account. Deadlines
for online assignments will be clearly stated on the homework website, and I will announce them in class.
Additional information regarding online homework:
• Go to http://www.math.tamu.edu/courses/eHomework/ to access your online homework (as well as tutorials for how to
use WebAssign).
• You have a “practice” version and a “homework” version for each assignment. You have 20 attempts for each question in
the practice version, and you have 3 attempts for each question in the homework version (you can submit the answer(s)
to each question individually).
• I will NOT be counting the “practice” versions for a grade. Only the “homework” versions will count for a grade.
• After submitting an answer in the practice version, you will see the correct answer. It is very important that you work the
practice version at least once so you will see the format you need to use for your answers in WebAssign.
• You should use Mozilla Firefox and have the most updated versions of Java and Flash on the computer you are using to
alleviate technical problems.
• If you ever have technical issues with WebAssign, please fill out the “Student Help Request Form” found at
http://www.math.tamu.edu/courses/eHomework/.
• I will not give an extension due to technical difficulties, so be sure to start your homework well in advance so that you
have time to resolve any technical issues.
Grading policy for online homework:
Due to the pace of the summer session, your online homework will be graded using a sliding scale (i.e., you do not have to get
all of the problems correct to receive a 100%).
In WebAssign, when you work a problem correctly, you will see that you have earned one point (partial points are possible for
questions with multiple parts). Since each homework has a different number of problems and we are using a sliding scale, each
homework will be worth a total of 10 points (regardless of the number of questions in the assignment).
The following categories are based on the number of questions in each homework. In each category, the number of WebAssign
points necessary to receive the corresponding homework points is shown. Remember, for each homework, you can receive
up to 10 homework points (this would mean getting a 100%). You will need to keep up with your homework grade for each
assignment since W.A. will only show the number of problems correct.
Homework has 16 or more questions:
W.A. Points
0
more than 0 but less than 2
2 or more but less than 4
4 or more but less than 6
6 or more but less than 8
8 or more

Example: The homework for section 1.5 contains 16 questions. After 3 attempts, W.A. shows you have earned 6.5 points (6.5
problems correct). Then, your homework grade is 8/10 (or 80%).
Example: The homework for section 5.6 contains 10 questions. After 3 attempts, W.A. shows you have earned 2 points (2
problems correct). Then, your homework grade is 5/10 (or 50%).
Example: The homework for section 6.4 contains 5 questions. After 3 attempts, W.A. shows you have earned 0.5 points (1/2 of
a problem correct). Then, your homework grade is 3/10 (or 30%).
Suggested Homework: A list of suggested homework problems from your textbook can be found on my web page. These
problems will not be collected for a grade, but completing them is essential to doing well in the course.
Attendance: I STRONGLY suggest that you make every attempt to not miss a single day of lecture. Falling behind in this
course can be very detrimental to your grade.
Scholastic Dishonesty: You are encouraged to work together on the suggested homework problems, but do not copy another students work. Copying work done by others, either in class or out of class, is an act of scholastic dishonesty and will be
prosecuted to the full extent allowed by University policy. Storing formulas or unauthorized programs in your calculator is also
an act of scholastic dishonesty and will not be tolerated. Using or having an unapproved program or any formulas stored in your
calculator during an exam will result in a zero on the exam. Always abide by the Aggie Code of Honor: An Aggie does not lie,
cheat, or steal or tolerate those who do. Please refer to Honor Council Rules and Procedures at http://www.tamu.edu/aggiehonor
for more information on academic integrity and scholastic dishonesty.
Extra Help: Please feel free to ask questions in class. If you need more help, come by my office during office hours or
make an appointment to see me. The Math Department also offers help sessions. Help sessions will begin the second week of
classes and have drop-in hours where you can get help with your homework or other problems. Also, the link to the problems
and solutions for the Spring 2013 Math 142 Week in Review is posted on our course web page. You should work as many
problems as you can so that you will be prepared for quizzes and exams.
ADA Policy Statement: The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides
comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities.
If you believe you have a disability requiring an accommodation, please contact the Department of Student Life, Services for
Students with Disabilities, in Room B118 of the Cain Hall or call 845-1637.
Copyright Policy: All printed materials including (but not limited to) handouts, quizzes, exams, and information found on
the web are protected by copyright laws. One xerox copy (or download from the web) is allowed for personal use. Multiple
copies or the sale of any of these materials is strictly prohibited and will be prosecuted to the full extent of the law.
