A. Precalculus is the study of elementary mathematical functions.
Among these functions are circular (trigonometric) functions, polynomial,
rational, exponential and logarithmic functions. Some consideration is also
given to power, direct variation, inverse variation, and logistics
functions. It is a Focus course (1 Credit) designed to prepare students for
Advanced Placement Calculus or College Calculus. Trigonometry and its
applications are the major topics in the first half of the course. Other
topics such as the algebra of functions, absolute value and non-linear
inequalities, conics, and a review of polynomial, rational, exponential and
logarithmic functions will follow. If time permits, topics such as
parametric equations, polar coordinates, sequence and series will be
introduced. Precalculus is not linked to other courses. However, there are
many mathematical connections to other areas of study such as physics,
chemistry, astronomy, navigation, surveying, engineering, etc. Using
graphic calculator, Geometer’s Sketchpad, Excel and/or computer software,
you will learn to apply Precalculus mathematics to solve real world problems.
B. Essential Question:
i. “What are elementary functions and how are they
used to solve real-world problems?”
ii. “How are circular functions used to model PERIODIC
phenomena in the real world?”
