For each chapter, the Online Study Guide consists of Module Formulas and a set of Practice Problems. The Module Formulas provides a list of the formulas contained in each chapter. Click the appropriate boxes to see each formula in words and symbols. Test yourself by hiding either the formula in words or the formula in symbols (or both). Check your understanding of each chapter by attempting the Practice Problems. A variety of question formats are used (e.g., true/false, multiple choice, fill in the blank) and the answers are provided.
