Discovery-based Investigations provide in-depth contextual content, real-life data, and the integration of technology to let students explore a problem before solving it Students analyze data, which they are given or gather themselves, to make sense of the mathematical relationships they observe Examples are fully worked out and include reasons that justify the process Support the use of graphing calculators, which let students easily manipulate large amounts of data and see the ?big picture? of the math being used Optional interactive Explorations, included on the Student CD, use Microsoft® Excel to build spreadsheets for Activities in which students investigate algebra concepts

Cynthis Young's Algebra & Trigonometry, Fourth Edition will allow students to take the guesswork out of studying by providing them with a clear roadmap: what to do, how to do it, and whether they did it right, while seamlessly integrating to Young's learning content. Algebra & Trigonometry, Fourth Edition is written in a clear, single voice that speaks to students and mirrors how instructors communicate in lecture. Young's hallmark pedagogy enables students to become independent, successful learners. Varied exercise types and modeling projects keep the learning fresh and motivating. Algebra & Trigonometry 4e continues Young's tradition of fostering a love for succeeding in mathematics.

This text provides a supportive environment to help students successfully learn the content of a standard algebra and trigonometry course. By incorporating interactive learning techniques, the Aufmann team helps students to better understand concepts, focus their studying habits, and obtain greater mathematical success.Prerequisite review is included in the textbook (and supporting materials) so that instructors can spend less time covering review material and students can still fill in the gaps in their mathematical knowledge.Integrated Review Notes provided next to examples throughout the text help students see the key prerequisite skills used within the example. For added convenience, these example-specific notes direct students to the page(s) where they can practice and review skills.Prepare for the Next Section Exercises, found at the end of the exercise sets, have been carefully selected to review the prerequisite skills students will need in the next section. Next to each exercise is a reference to a section of the text where students can go to review topics they don't understand.Interactive reading and study support is provided through careful placement of a Question/Answer feature throughout the exposition of the text so that students can check their understanding of concepts, think more critically about the mathematics, and more actively engage in learning mathematics. To support students studying independently, the answer to each question is conveniently provided as a footnote on the same page as the question.To create a link between the algebraic and visual representations of a solution, increase students' understanding of the concept presented, and accommodatedifferent learning styles, the authors have provided both an algebraic solution and a graphical solution (represented by either a coordinate grid graph or a graphing calculator screen) for appropriate examples.Focus on Problem Solving at the beginning of every chapter reviews and demonstrates various strategies used by successful problem-solvers.Special modeling sections throughout the text, which rely heavily on the graphing calculator, provide an opportunity to motivate students with relevant, modern applications. These special sections introduce the idea of mathematical modeling of data through linear, quadratic, exponential, logarithmic, and logistic regression. Students are often required to work with tables, graphs, and charts using data drawn from a variety of disciplines.

Automatically packaged with every new book, the ever-popular DVC features the author, Pat McKeague, working parallel problems for every concept in the text. The CD contains over 8 hours of digital video. The core of each DVC is instruction, so each section of the book is covered by a 5- to 10-minute video lesson. The problems worked during the video lesson are listed next to the viewing screen, so that students can work them ahead of time by themselves. A slider bar is included with the viewing screen to give immediate access to any part of the video lesson. Also included on the CD-ROM is the MathCue Tutorial software, which presents and scores problems and tutors students by displaying annotated, step-by-step solutions.
