Larson's PRECALCULUS: A CONCISE COURSE is known for delivering the same sound, consistently structured explanations and exercises of mathematical concepts as his market-leading PRECALCULUS, Ninth Edition. In A CONCISE COURSE, the author offers instructors a streamlined presentation to precalculus that is a perfect one-semester alternative to traditional textbooks. With the third edition, Larson continues to revolutionize the way students learn material by incorporating more real-world applications, ongoing review, and innovative technology. How Do You See It? exercises give students practice applying the concepts, and new summarize features, checkpoint problems, and a companion website reinforce understanding of the skill sets to help students better prepare for tests. Enhanced WebAssign features fully integrated content from the text, with the addition of end-of-section problems and chapter tests, as well as problem-specific videos, animations, and lecture videos.
