Overview

Engage your students and prepare them for success in your course and the future with the student-focused approach of Ron Larson’s “Trigonometry” with WebAssign. Updated with the purpose of giving students every chance to succeed, the 12th edition streamlines the presentation to emphasize and reinforce key concepts while eliminating any distractions. Students overcome preparedness gaps at the beginning of the term with Larson’s review material and the College Math Readiness Bootcamp in WebAssign. Students then stay on track with continual reinforcement of key skills with the Review & Refresh exercises and new Getting Ready for the Chapter sections. Taking their understanding to the next level, students apply mathematical concepts with Exploring the Concepts sections, How Do You See It? exercises and Explore It interactive learning modules.
