MAT-125-20, Elementary Math Models (SP15)

INSTRUCTOR: Radhakrishnan Palaniswamy (Krish), Phone: 443-322-4028 (cell), Email: rpalaniswamy@ndm.edu

SCHEDULE/DAY/TIME: Semester/Saturday/12:00 - 2:45 PM, 01/31/2015-05/16/2015


An introduction to the methods used in applying mathematics to real problems from the physical life and social sciences.  Applications will be investigated numerically and graphically using a graphing calculator before the mathematical model is expressed algebraically.  Algebraic concepts will be reviewed and developed as needed.  This course will help students refresh and strengthen their mathematics and increase their understanding of its usefulness.

-Mathematical Association of America:  1997.

-A graphing calculator will be needed.  It should be a TI-83 Plus, TI-83, or TI-84.

Please note that cell phones and PDA’s may not be used as calculators during an exam.


To enable the student to

  1. explore a variety of basic and useful mathematical models;
  2. strengthen and extend basic algebra skills;
  3. utilize a graphing calculator as a tool in understanding mathematical models;
  4. learn by collaborative work with other students;
  5. develop confidence in her mathematical judgment.


In general, each class will include time for questions on homework and for guided problem solving as well as for the presentation of new material.


There will be two tests and a comprehensive final exam.

Homework will be assigned for each chapter we cover.  Late homework will be accepted if received by the next class but will be penalized by 20%.  Homework that is later than that will not be accepted for a grade.

We will have time during several classes designated for collaborative work.  During these classes you will work in groups on problems designed to help you integrate and extend the material you have been studying.  If a collaborative assignment is missed, the work is to be completed in a timely fashion; however, full credit will not be given.    

Students are required to be registered for the Joule site for this course.


Students are expected to attend every class on time and will be held responsible for any material covered, any announcements made in class, and any changes in the schedule whether they are present or not.

If you have a legitimate reason for missing a test, I must be contacted before the testing has taken place.  If I cannot be reached, leave message via phone or email.  Otherwise a make-up will not be given unless there is a documented emergency.  Any make-up must be taken before class within a week of the original test date.  Only one make-up test may be taken.  Any missed test that is not made up will result in a grade of zero.

Grades will be determined as follows:

Homework: 20%; Collaborative Assignments: 20%; Exams: 40%; Final Exam: 20%

A=90% or above; B+=87% -89%; B=80% - 86%; C+=77% - 79%; C=70% - 76%; D=60% - 69%; F=Below 60%

No extra credit will be given in this class.
