The Definitive User's Guide to the HP 48g/49g/50g Calculators
HP provides an impressive quantity of user documentation, but quantity is no guarantee of quality! Tom Barber has been a professional programmer of the C/UNIX persuasion for more than 25 years, hooked on HP calculators since his college days when he implemented Gaussian quadrature on the HP25. The reputation of HP calculators as being somewhat difficult to use, has a lot to do with the user documentation. That is why he wrote this book.
Written primarily for novice users, experienced users who occasionally find themselves frustrated may also find help within the pages. The author takes a tutorial approach for certain topics such as the Equation Writer, and overall, his narrative explanations are better organized and more complete than HP's manuals. He uses tables and lists for topics where a more accessible summary of essential facts and behaviors is needed. He paid careful attention to the importance of writing in a clear, precise manner.
Topics covered include:
Essential Architectural Features
Keypad operation
Essential calculator modes
What the CAS modes Numeric and Approx actually do
