In order to take MAT 123, you must have either- passed MAP 103 with a C or better, or
- received level 3 or better on the mathematics placement examination.

See the document
first year mathematics at Stony Brook for more information
about the math placement exam and other calculus courses.
**Please note.** The prerequisite must have been satisfied within
one year prior to beginning the course.

## Course Learning Objectives

Successful completion of this course with a grade of C or higher satisfies the DEC C and SBC QPS requirements. The course learning objectives include the following.-
**Interpret and draw inferences from mathematical models such as formulas, graphs, tables, or schematics.**This includes understanding the features of different formulas / graphs such as linear formulas / lines (slope and intercepts), trigonometric formulas (period, peaks, troughs, amplitude, ...), and quadratic functions (vertex of a parabola, ...), as well as more general features (domain and range, discontinuities, vertical and horizontal asymptotes, etc.) -
**Represent mathematical information symbolically, visually, numerically, and verbally.**This includes graphing functions given as equations, converting between different descriptions of functions (e.g., explicit equations versus implicit descriptions such as inverse functions), and finding the appropriate equations and graphs from a verbal description (i.e., "word problems"). -
**Employ quantitative methods such as algebra, geometry, calculus, or statistics to solve problems.**Students will learn how to use models such as linear models and exponential models to understand real-world phenomenon such as compound interest, population growth, and radioactive decay. -
**Estimate and check mathematical results for reasonableness.**Students will learn how to perform "consistency checks" to test solutions, e.g., plugging in points to check the equation of a graph obtained from an affine linear transformation (horizontal / vertical translations and scalings). -
**Recognize the limits of mathematical and statistical methods.**Students will learn the limits of simplified mathematical models (such as exponential population growth).

- Understand the domain and range of a function.
- Know when a function is invertible, and find the inverse of an invertible function. Understand the relationship between the domain and range of an invertible function and its inverse function.
- Perform vertical and horizontal transformations (translations, scalings and reflections) of functions and graphs.
- Compose functions. Graph composite functions.
- Know the standard forms for equations of lines. Recognize parallel and perpendicular lines.
- Know the quadratic formula and "completing the square".

- Know the inverse trigonometric functions, including their domains and ranges.
- Understand transformations of trigonometric functions, e.g., amplitude and phase shift.
- Understand logarithms as inverses of exponential functions. Know the logarithm laws and how to use them.
- Understand models using exponential and logarithmic functions: population growth, interest, radioactive decay.
- Understand rational functions, including domains.
- Graph rational functions.

## Course Requirements

### Attendance and Make-Up Policy

- Students are expected to regularly attend lecture and recitation.
- Problem sets and exams that are missed may only be excused with a valid excuse, including a doctor's note or other such documentation.
- In most circumstances, an excused midterm will be discounted in the computation of the final course points; no make-up will be offered, but the remaining midterm and final exam will be weighed more to bring the exam portion of the grade to the correct level.
- Since the core competency exams are offered multiple times, a missed core competency exam will usually be ignored: the student may make-up a missed core competency exam when it is next offered.
- Extensions of deadlines for WebAssign are handled within the WebAssign system. This semester, unexcused late assignments are accepted, but with an automatic penalty of 33% each day late (thus no credit after 3 days).

### Readings and WebAssign

Please follow this link for the calendar of assigned readings and WebAssign assignments.### Exams

- There will be three core competency exams; short
multiple choice / short answer exams that test competency of the core
material. Students
**must**pass these exams in order to earn a grade of C or higher. - We are attempting to computerize the core competency exams, so
that students may take proctored exams in a testing center at
convenient times. However, until that is finalized, tentatively the
core competency exams are scheduled for the following dates
**in lecture**. - Core Competency Exam A, In-Lecture: Wed 2/18 Lec 01 & 03, Thu 2/19 Lec 02. There is now a practice exam for Core Competency Exam A. There are now solutions to the practice exam for Core Competency Exam A; the solutions correct some typos on the original practice exam.
- Core Competency Exam B In-Lecture: Wed 3/25 Lec 01 & 03, Thu 3/26 Lec 02. There is now a practice exam for Core Competency Exam B. There are now solutions to the practice exam for Core Competency Exam B.
- Core Competency Exam C In-Lecture: Wed 5/6 Lec 01 & 03, Thu 5/7 Lec 02.
- Midterm 1 was held at 8:45pm, Thursday, February 26.
There are now solutions to Midterm 1.
The room for
Recs 01, 02, 03, 05 and 12 was Harriman Hall 137. The room for Recs
06, 07, 08, 09 and 10 was Frey Hall 102. The room for Recs 13, 14 and 15
was Frey Hall 104.

Midterm 1 included a second attempt at Core Competency Exam A for those students who had not yet passed Core Competency Exam A. In addition, Midterm 1 included a*Mastery Exam*testing deeper understanding (worth 10% of total class points). Here is a practice for the Mastery Exam. Here are solutions to the practice mastery problems. Midterm 1 from previous semesters also gives good preparation for the Mastery Exam (Fall 2013, Fall 2012), although we have not yet reached the same point in the text as in previous semesters. - Midterm 2 was held at 8:45pm, Tuesday, March 31.
There are now solutions to Midterm 2.
The room for Lec 01 as well as Rec 07 was (Old) Engineering 143. The
room for Rec 06, 08, 09 and 10 was Frey Hall 102. The room for Lec
03 was Earth and Space Sciences 001. Midterm 2 included additional
attempts at
Core Competency Exam A and Core Competency Exam B for those students
who had not yet passed one of these. In addition, Midterm 2
included a
*Mastery Exam*testing deeper understanding (worth 10% of total class points). Here is a practice for the mastery portion of Midterm 2. There are now solutions to the practice mastery questions. - The Final Exam will be held 8 — 10:45am, Wednesday, May 13.
- For Core Competency Exam A, a second attempt will be allowed during Midterm 1. For Core Competency Exam B, a second attempt will be allowed during Midterm 2. For Core Competency Exam C, a second attempt will be allowed during the Final Exam.
- Apart from the second attempts of the core competency exams, the remainder of the midterms and final exam will be long-form problems, typically with multiple parts that build on each other and that test mastery of the subject.

### Textbook

*Precalculus: A Prelude to Calculus, Second Edition*, by Sheldon Axler available at the University Bookstore @ Stony Brook. The course material bundle from the bookstore includes an access code for WebAssign, which we will be using this semester. You are free to purchase the textbook elsewhere, but then you will need to buy stand-alone access for WebAssign. You can get electronic access to the text together with WebAssign access at WebAssign. Students are

**encouraged**to explore all options to find the best value in purchasing course materials.

## Grading System

**Core Competency Exams.**

- These are three multiple choice / short answer exams: Core Competency Exam A, Core Competency Exam B, and Core Competency Exam C. See here for more details.
- These exams test competency in the core material of the three units of this course.
- Each student will have at least two opportunities to pass each of the three core competency exams.
- In
order to receive a grade of C or higher, students
**must**pass each of the three core competency exams. Passing the three core competency exams will automatically qualify students to receive a grade of at least C in the course. Students who do not pass the three core competency exams cannot receive any grade higher than C-. - For letter grades above C, passing the core competency exam
counts for 60% of the total class points.
**Letter Grades Above C**Those students who pass the three core competency exams automatically receive a grade of at least C. Letter grades above C are determined based on total class points. The relative weighting of class points are as follows.Core Competency Exams 60% Midterm I 10% Midterm II 10% Final Exam 15% WebAssign Assignments 5% ## Meeting Schedule

### Lectures

Primary instruction will occur in lectures, with practice and reinforcement provided in a smaller classroom setting during recitations.

### Cell Phones and Electronic Devices

Students should be attentive and respectful during class. Students should not speak on cell phones during class, and students should keep cell phone noises to an absolute minimum. If it is absolutely necessary to make a phone call, students should exit the classroom before placing or answering the call. Similarly, although students are allowed to use laptops and other electronic devices, these must be unobtrusive, quiet, and they must not distract other students or the instructors.**Cell phones and all other electronic devices may never be used during exams.**### Handbacks

Graded problem sets and exams will be handed back in recitation. If you cannot attend the recitation in which a problem set or exam is handed back, it is your responsibility to attend your recitation instructor's office hours and get your graded work.

**FAILURE TO RETRIEVE GRADED WORK IS NOT GROUNDS FOR A MAKE-UP, A REGRADE, OR CHANGE OF A FAIL TO AN INCOMPLETE.**

You are responsible for collecting any graded work by the end of the semester. If you have a question about the grade you received on a problem set or exam, you must contact the recitation instructor (not the grader or the lecturer).## Academic Resources

There are a number of organizations on campus offering tutoring and other academic resources in various locations. The mathematics department offers drop-in tutoring in the Math Learning Center. You are strongly encouraged to talk to a tutor in the MLC if you have an issue and are unable to attend your lecturer's or recitation instructor's office hours (or if you have previously arranged to meet them in the MLC).Please be aware that tutors in the MLC deal with students on a first-come, first-served basis. Thus it may be preferrable to speak with your lecturer or instructor in their office hours. (Even if you find them in the MLC, they may be obliged to speak to other students before speaking with you.)

Many additional tutoring resources are listed on the ASTC webpage. For students living on campus, there are also tutoring centers available in the residence halls.

## Disability Support Services

If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, ECC (Educational Communications Center) Building, room 128, (631) 632-6748. They will determine with you what accommodations, if any, are necessary and appropriate. All information and documentation is confidential.Students who require assistance during emergency evacuation are encouraged to discuss their needs with their professors and Disability Support Services. For procedures and information go to the following website: http://www.stonybrook.edu/ehs/fire/disabilities.

## Academic Integrity

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Technology & Management, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at http://www.stonybrook.edu/commcms/academic_integrity/index.html.## Critical Incident Management

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Faculty in the HSC Schools and the School of Medicine are required to follow their school-specific procedures.
