# MATH 146 Syllabus

### Precalculus

Revised: January 2015

## Course Description

Functions using equations, graphs, and numerical data; linear, exponential, logarithmic, trigonometric, polynomial, and rational functions; transformations, compositions, inverses, and combinations of functions; trigonometry with identities. Prerequisite: MATH 130. Four semester hours

## Student Learning Objectives

By the end of this course, students will be able to:

• Interpret functions as mathematical models in numerical, graphical, and algebraic forms;
• Recognize basic properties and graphs of elementary functions and will use transformations to graph functions;
• Identify characteristics of graphs of linear, exponential, logarithmic, polynomial, rational, and trigonometric functions;
• Solve exponential, logarithmic, polynomial, rational, and trigonometric equations;
• Describe the concept of inverse functions and perform inverse operations with some elementary functions, as well as exponential, logarithmic, and trigonometric functions;
• Apply trigonometric functions in terms of both the right triangle definition and the circular definition;
• Manipulate trigonometric expressions in order to verify trigonometric identities and solve trigonometric equations; and
• Use technology appropriately in the evaluation, analysis and synthesis of information in problem-solving situations.
