Course:  MATH 1301 (College Algebra) [3-3-0]

Spring  2008 Math 1301 Syllabus

Instructor: Dr. E. DeLaVina; Office: S712; Email: delavinae@uhd.edu; Phone: 713-226-5241

Office Hours: Mon. & Wed 2:30-3:30 and other times by appointment

Catalog Description:  College-level topics in algebra including variation, systems of equations and inequalities, nonlinear inequalities, functions and their graphs, lines, quadratic equations and functions, complex numbers, polynomials, exponential and logarithmic functions, the algebra of functions, an introduction to plane analytic geometry, and applications related to these topics. (MATH 1314)

Prerequisite:  A grade of “C” or better in MATH 1300, or placement by exam taken at UH-Downtown, or a score of 270 on the math section of THEA or 73 on Accuplacer. You do not need to purchase a graphing calculator, but you should have access to a scientific calculator throughout the course. A scientific calculator is one that includes “ln” and “log” keys.

Purpose:  This course provides the background in algebra necessary for further study in college-level mathematics and its applications.

Audience:  This is a college freshman-level mathematics course, which requires a background consisting of two years of high school mathematics or MATH 1300.

Textbook:  College Algebra with Modeling and Visualization, 3rd Edition, by Gary K. Rockswold, Addison-Wesley, Boston, MA, 2008. For emergency situations, a copy of this book is kept on reserve in the UHD Library and the Math Lab (N925).

Some Departmental Policies Regarding This Course:

1.      Each instructor must cover all course topics by the end of the semester. The departmental final exam is comprehensive and questions on it can deal with any of the course material.

2.      Each student is expected to purchase or otherwise have access to a scientific calculator throughout the semester and will be allowed to use a scientific calculator on the final exam. Graphing calculators are not required and the advanced features of a graphing calculator should not be used on any exam.

Statement on reasonable accommodations: UHD adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with disabilities.  Students with disabilities should register with the office of Disabled Student Services and contact me in a timely manner to arrange for appropriate accommodations.

Please remember that as a member of the UHD academic community you are bound to observe the academic honesty code in all your school work. A grade of 0 will be given for any course work where cheating is detected.
