## Description of Course Content

This course will cover function notation, basic graphing techniques, polynomial, rational, exponential, and logarithmic functions.  Applications of the mathematics will be stressed.  A graphing calculator is required, preferably a Texas Instruments TI-83 Plus, TI-83 or a TI-82. Students will be taught:

Chapter 2-Functions and their Graphs

Definition of a relation, Domain of a function, Increasing/decreasing intervals for a function, Symmetry of functions, Graphs of basic function

Chapter 3-Polynomials and Rational functions

Graphing by transformations, Quadratic functions-vertex, axis of symmetry, intercepts, etc., Polynomial functions-degree, multiplicity of zeros, shape, intercepts, graphing, etc., Rational functions-domain, vertical, horizontal, and oblique asymptotes, Finding zeros of polynomial functions-rational, real, and complex

Chapter 4-Exponential and Logarithmic functions

Inverse functions-test for one-to-one functions, graphing a function and its inverse, finding the inverse function and checking to see if it is the inverse (composition of functions), Exponential functions-domain, properties, exponent laws, solving exponential equations, Logarithmic functions-domain, properties, theorems, solving logarithmic equations

Chapter 8-Systems of equations and inequalities

Systems of equations-3 methods for solving, types of solutions, Systems of inequalities-solution, corner points, boundedness, solve a linear programming problem

Chapter 5-Trigonometric functions

Angles and their measure, trig functions/unit circle, right triangles, graphs of trig functions, inverse trig functions

Chapter 6-Analytical trigonometry

Verifying trig identities, sum and difference formulas, double/half angle formulas, trig equations

Chapter 7- Additional topics in trigonometry

Law of sines, law of cosines, polar equations, graphs of polar equations, complex numbers in polar form

### Rating

There will be 6 tests @ 75 points each and a comprehensive Final @ 100 points. The total possible points earnable will be 550.  Grades will be assigned on a point scale format:

#### B = 440-494

C = 385-439

D = 330-384

F = 0-329

###### Attendance Policy

Attendance is mandatory to do your best in the course.  I will attempt to take the roll daily.  If you miss more than 5 times (following the last day to drop the course) you will automatically be dropped from the course.

Cheating or any other behavior that is disruptive in the class will not be TOLERATED.  If you are caught cheating on a test you will be given an F.

No make up exams will be given.  If you miss a test you will wait until the final exam to get a  make-up grade.

THE DEADLINE TO DROP THIS CLASS WITHOUT PENALITY (YOU RECEIVE A W) IS February, 27th.
