Book Description Updated and expanded to include the optional use of graphing calculators， this combination textbook and workbook is a good teach-yourself refresher course for men and women who took a calculus course in school， have since forgotten most of what they learned， and now need some practical calculus for business purposes or advanced education. The book is also very useful as a supplementary text for students who are taking calculus and finding it a struggle. Each progressive work unit offers clear instruction and worked-out examples. Special emphasis has been placed on business and economic applications. Topics covered include functions and their graphs， derivatives， optimization problems， exponential and logarithmic functions， integration， and partial derivatives.
