Additional Course Description:

Math 115 - Precalculus, is designed to prepare students for Math 221, Calculus. Math 115 is an in-depth study of the concept of functions.Several function classes including linear, quadratic, polynomial, rational, exponential, logarithmic, and trigonometric functions are studied. Within each function class characteristics of the function are emphasized including the basic form and graph, equations and inequalities associated with the function, and applications. Both algebraic and graphical techniques will be used throughout the course. Appropriate prerequisite skills and understandings for this course are required for success in this course. Details are discussed in the course prerequisites below. Students who need to review algebra should register for M010.

Students who are planning on taking Math 241 Analytic Geometry and Calculus A should enroll in Math 117 - Precalculus for Scientists and Engineers, not Math 115. Math 115 will not sufficiently prepare students for Math 241. In addition, students unsure of their mathematics requirements for his/her major may wish to consult their advisor – Math 114, Math 113 might be more appropriate.

Although most students have studied precalculus in high school and many may have studied calculus, there are several important distinctions between high school and university mathematics courses that you should note:

The pace of the course is considerably faster than most high school courses.

You are expected to spend significant time outside of class reading the text, doing homework problems, and preparing yourself to participate in class. The amount of time needed for this course may come as a surprise to many students.

To succeed in this course, students need "extensive" algebra skills. Yet, many students coming from high school (even students who had calculus) do not have appropriate algebra skills. (See more details below under prerequisites.) There is very little time devoted to review of algebra topics. Students must have the appropriate background to succeed in this course.

Usually several sections of this course are offered during the fall and spring semesters. Common exams are administered in the evenings.

Course Content:

The following list illustrates the topics intended for coverage in a typical semester. Chapter references apply to the current textbook. Your instructor may cover these topics in a different order or may add topics if necessary.

M115 General Syllabus (Fall 2011) **Links to sample exams:** Exam 1 - 09F Exam 2 - 09F Exam 3 - 09F Final Exam - 09F **Required Math Placement Test Level:** P, S, B, C**Additional Prerequisite Discussion:**

It is expected that M115 students have a thorough understanding of algebra topics. Experience has shown those students who enroll without these important algebra skills and understandings will not succeed.

The following are the textbooks typically used in this course. Other University of Delaware campuses may use different textbooks. Students should wait until the first day of class to ensure the appropriate textbook and other course materials are purchased.

Blitzer, Precalculus Essentials, Prentice Hall, Third edition, including access to MyMathLab

A graphing calculator is required. The TI-83, TI-83+, TI-84, TI-84+ graphing calculator is recommended. You may not use a TI-89, TI-92+ or Voyage 200 on exams. While it is permissible to use another brand of graphing calculator, you must know how to use it. Your instructor will use a TI-83+ or TI-84+ for classroom instruction. Note that calculators such as the TI-86 are not compatible.

The graphing calculator is an important tool for exploring and understanding the mathematical concepts in this course. It will be used in class, for homework assignments, and will be required on exams. Always take your calculator to class. It is your responsibility to insure that your calculator is working properly during examinations and to know how to use its features. Calculators will NOT be provided.

Assessment activities generally include tests or quizzes or other course activities as determined by the instructor. Since this is a multi-section class, usually three common exams and a common cumulative final are administered. Other assessment activities such as quizzes, group work, textbook assignments may also be required. An example can be found in the sample syllabus.
