# Math 113 syllabus

## Precalculus Trigonometry

Bulletin Description

Continuation of MA 112. Topics include numerical, graphical and algebraic properties of trigonometric functions, inverse trigonometric functions, right angle trigonometry, parametric equations, polar coordinates, and conic sections. Development and application of mathematical models to real-world situations is emphasized. Credit for both MA 113 and MA 115 not allowed. Core Course.

Course Pre-requisites  C or better in MA 112, or a sufficient Mathematics Placement Exam score, or a sufficient ACT Mathematics subscore.

Text Precalculus: A Right Triangle Approach 4th edition, Beecher, Bittinger, Penna

Calculator A Texas Instruments TI30XII-S scientific calculator is required.

Goals and Objectives

• Understanding of trigonometric functions in terms of arc length on unit circle and in terms of ratios of lengths of sides in a right triangle.
• Algebraic skills necessary to solve equations involving trigonometric functions and to obtain standard forms for conic equations.
• Reasoning and sketching skills for survey and bearing applications of trigonometry and for reading standard form equations for conics from graphs or graphing these from equations.
• Graphing trigonometric functions emphasizing amplitude,  period,  phase and vertical shifts as they correspond to stretch, compression and shifts discussed in MA 112.
