MAT 123 (Pre-Calculus)-Fall 2018 (This is NOT the online version of the class)

Course Description: This course begins with what are often referred to as the transcendental functions. We will cover trigonometric functions and their applications to complex numbers. We will then turn to the natural logarithm (ln(x)) and the extremely important number e. The course will end with an introduction to rational functions which is an excellent introduction to calculus. If you need extensive work with polynomials, linear functions, and introductory functions, it is recommended that you consider taking MAP 103 instead of this class. Calculators will not be used this semester.
