Precalculus Mathematics
I. Course Description
This is a 4credit hour course. The prerequisite for this course is qualification
through
placement. The material for this course is precalculus: equations and
inequalities, functions and
their graphs, exponential and logarithm functions, polynomial and rational
functions,
trigonometric functions and analytic trigonometry. Students may not receive
credit for both Math
111 and Math 115 or both Math112 and Math 115.
Goals and Learning Outcomes
The overall goal of Math 115 is to make students understand mathematical
concepts using
realworld data and questions. The measurable learning outcomes
used to determine the
degree to which this goal is being met follow:
Students will solve linear and quadratic
equations.
Students will review the Cartesian plane: they will calculate the distance and
midpoint
between two points.
Students will plot graphs of equations.
Students will be able to determine if a relationship is a function, if
functions are oneto
one, graph functions, and perform operations and
composition of functions.
Students will divide polynomials using both long and synthetic division.
Students will factor polynomials, determine zeros of polynomials and graph
polynomial
and rational functions.
Students will graph exponential functions and their inverses, logarithmic
functions.
Students will use their properties to solve exponential and logarithmic
equations
Students will define trigonometric functions three ways.
Students will graph trigonometric function and solve applications involving
trigonometric functions.
Students will verify trigonometric identities and solve trigonometric
equations.

The Academic Success Center is a free tutoring lab, located on the second floor
of Medford
Library. I will give you a handout with more information as soon as
it’s available (probably
next week).
WileyPLUS Technical Support
WileyPLUS TwoMinute Tutorials
Student Solutions Manual/Additional Homework
If you feel like you need more practice, you may do homework from the textbook.
WileyPLUS
provides a student solution manual that contains solutions to Algebra
Aerobics and to the odd
numbered exercises. To access it, log in to WileyPLUS.
Go to Read, Study and Practice. Choose
the appropriate chapter. Scroll down to
Student Hints and Solution Manuals.
Additional WileyPLUS Homework
I provided some additional problems on WileyPLUS. You will not receive any
credit for
competing these. However, some of you will find that you need the
extra practice in order to
better prepare for the tests.
Office Hours
You are always welcome to come to my office hours. You can also make an
appointment to
meet at some other mutuallyconvenient time.
