Part of the Trigsted Precalculus Series, Trigonometry is a completely clickable eText with a consistent author voice, created from the ground up within MyLab Math. Recognizing that students start with homework instead of reading the text, Kirk Trigsted created an online learning environment that blends exposition, videos, interactive animations, tutorials and assessment, designed for the way you think and behave online. All exercises, feedback and content are written by the author himself, ensuring a consistent, reassuring author presence throughout and promoting productive use of course materials. Along with many other enhancements, the 3rd Edition expands the exercise program with over 1200 new and updated exercises that help you make the most of your time spent on homework.
