Course Overview

Introduction to Plane Trigonometry

This course, MAT 103 – Plane Trigonometry, provides a one-semester introduction to the study of triangles and periodic functions. The curriculum covers the fundamentals of trigonometric functions, their applications, graphs, identities, and solving equations involving these functions. The course is designed for students who have completed MAT 101 or have a qualifying mathematics ACT score.

• Prerequisite: MAT 101 (grade C or better) or ACT score ≥ 24

• Textbook: Trigonometry, 12th Edition by Lial, Hornsby, Schneider, and Daniels

• Calculator: ACT-approved scientific calculator (e.g., TI-30XS Multiview)

• Online Access: Pearson MyLab&Mastering (MLM) required

Course Structure and Assessment

Instructional Format

The course is delivered through lectures, discussions, and problem-solving sessions. Assessments include in-class tests, quizzes, online homework, and a comprehensive final exam. Students are expected to utilize resources such as guided notes, Pearson videos, and the Mathematics Tutoring Center.

• In-class assessments: Tests and quizzes

• Online assignments: MLM Homework and Quizzes

• Final Exam: Comprehensive, covering all major chapters

Grading Policy

Grades are determined by weighted averages of tests, homework, quizzes, and the final exam. The grading scale follows a standard 10-point system.

Grading Scale:

Sample Grade Calculation:

• Tests average: 71 × 0.50 = 35.5

• Homework average: 90 × 0.15 = 13.5

• Quizzes average: 85 × 0.15 = 12.75

• Final Exam average: 75 × 0.20 = 15

• Total: 35.5 + 13.5 + 12.75 + 15 = 76.75 (C)
