## Course Description

MAT 123 is a thorough preparation for the calculus sequences at the University at Stony Brook (MAT 125-127, MAT 131-132, and AMS 151-161). Its primary objective is strengthening students' grasp of the mathematical tools needed for calculus: functions, graphs, polynomials, exponentials, logarithms, trigonometry, and their applications. Towards the end of the course the first fundamental concepts of calculus (limits and derivatives) will be examined as part of a transition to the beginning of MAT 125, 131 or AMS 151.
• If you need one semester of mathematics to satisfy the DEC "C" requirement, take MAT 118.
• If you need one semester of calculus, for example for the BUS major, take MAT 122.
• MAT 123 exists only as an introduction to the calculus sequences, and is not appropriate as a "stand-alone" course.

The fundamental objects of study in mathematics are functions. The approach taken in MAT 123 is to present and analyze functions from several points of view: as symbolic formulae, as graphs, as numerical data, and as relationships between quantities arising in applications. Similarly, the concepts of calculus are studied from these vantage points. All of these approaches to understanding are essential.

Prerequisites: Students in MAT 123 must have received a score of 3 or better on the Mathematics Placement Examination (MPE) administered by the Department of Mathematics to all incoming freshmen. If you received a lower MPE score, take courses such as MAP 101 and MAP 103 to improve your performance on the MPE. (For more information, refer to the document ``First Year Mathematics at Stony Brook.'')

Text: The required textbook is Selected Chapters from Precalculus: Math for Calculus and Single Variable Calculus, Concepts and Contexts by James Steward. It comprises selected chapters from two books by James Stewart: Precalculus, Chapters 1-7; and Calculus: Concepts and Contexts, Single Variable, Chapters 1-3. The textbook is intended to be read. Read the assigned sections before the lecture! Reading the textbook will greatly increase your comprehension and enable you to ask intelligent questions in class. Furthermore, the lecturers and recitation instructors will not always be able to cover all of the subject material for which you will be responsible.

Examinations: The course examinations are common to all sections of MAT 123. There will be two evening examinations and a final examination, scheduled as follows.

 Midterm Exam I: Monday, Oct 14 08:30 - 10:30 pm Midterm Exam II: Tuesday, Nov 12 08:30 - 10:30 pm Final Exam: Monday, Dec 16 02:00 - 04:30 pm
