Course Description
Together with Geometry and Algebra 2, the Precalculus elective prepares students for college-level work in calculus and other mathematics classes as well as classes in quantitative fields such as the social sciences, the natural sciences, and engineering. Central concepts are mathematical analysis, functions and their graphs, trigonometry, and linear algebra. Mathematical ideas are communicated using graphical, numerical, algebraic, and verbal approaches. Through mathematical modeling, concepts are applied to problems in physics, chemistry, biology, economics, and many other disciplines. Upon successful completion of this course, qualified non-seniors may take the Calculus elective.
Required text and supplemental materials
- Larson, Ron and Robert Hostetler, Precalculus, 5th Edition, Boston, MA: Houghton Mifflin, 2001. ISBN: 0-618-05285-2. Ordered by school. Required. Note: this is the 5th edition.
- Web searching, wikipedia.org and reputable websites such as Ask Dr. Math (http://mathforum.org/dr.math/) and Paul's Online Math Notes (http://tutorial.math.lamar.edu). Strongly recommended.
- Texas Instruments TI-84 Graphing Calculator (Plus and Silver Editions are OK). TI-Nspire with a TI-84 faceplate is also acceptable (but slow to boot and drains batteries quickly). TI-83 is workable (but check with teacher first). Required.
- Laptop computer. From time to time students who have access to a laptop computer may be asked to bring it to class. A small number of school laptops can be checked out, if available for that class. Strongly recommended.
- Rechargeable AAA batteries for the calculator and a battery charger (AA/AAA). Recommended.
- Organizer of paper: holes punched and not; pencils (mechanical recommended).

| Mid-Semester Tests: written and graphical solutions of problems from recent material. | 200 points per test |
| End-Semester Examinations: written and graphical solutions of problems from the whole semester (comprehensive). | 20% of course grade |
| In-Class work: positive energy and interest level during in-class work including discussion, working on investigations, and practice during class. Assessed informally. | 20 points per week |
| Commitment to learning: Taking on what is challenging to you, getting help, communicating with the teacher, engaging with the material, and documenting work in the notebook. Assessed informally. | 100 points per semester |
| Projects: quality and correctness of written and graphical results. | 100 points per project |
I encourage study groups. You may work with others (not just students) unless instructed otherwise as long as all of you contribute. It is wise to put the name of each contributing student on an assignment to avoid issues with plagiarism.
