MAT 145 - Precalculus 1

3 credit hours - Three hours weekly; one term.
Formerly MAT 141 - College Algebra and Trigonometry 1

This course meets the Mathematics General Education Requirement

Learn college algebra and introductory trigonometry. Algebraic topics include multiple representations of polynomial, rational, exponential, and logarithmic functions, systems of equations and related graphs, equations, inequalities and applications. Trigonometric topics include an introduction to angle and radian measure, right triangle relationships, trigonometric functions of any angle, laws of sines and cosines, graphs, applications and trigonometric equations.

Prerequisite(s): Achieve an appropriate score on the mathematics part of the ACT or SAT, or score at an appropriate level on the Mathematics Placement Test, or completion of MAT 012,  MAT 012E, or MAT 013A or MAT 045  with a grade of at least C.

Note: MAT 045  may be taken in the same semester as MAT 145; a grade of at least C is required in MAT 045  in order to start MAT 145.

Credit is not given for both MAT 145 and MAT 137  or for both MAT 145 and MAT 151 . Typically offered at MC, AM, GB, and OL; all terms.

Course Outcomes:

• Solve absolute value, quadratic, rational, logarithmic, exponential, and trigonometric equations.
• Solve linear, quadratic, and absolute value inequalities.
• Graph linear, polynomial, piecewise, rational, logarithmic, exponential and trigonometric functions.
• Apply polynomial, logarithmic, exponential and trigonometric functions to problems from business, the social sciences and the natural sciences.
• Perform algebraic operations on functions.
