Recognizing that today s students start with the homework instead of reading the text, Trigsted created an online learning environment that is a seamless mix of exposition, videos, interactive animations, tutorials, and assessment. This approach leverages the power of MyMathLab and leads students to interact with course materials in a way that is proving to be more effective. With Precalculus: A Right Triangle Approach, Trigsted continues to innovate with a revised design that improves navigation and usability, expanded videos, and increased animation coverage. All multimedia elements, exercises, feedback, and content are written by the author himself so that the students have a consistent voice throughout."
