Graphing Calculator Improves Connectivity

September 20th, 2006

With all the computing power we have now, I find it interesting that companies are still developing handheld calculators. I wish I had this as a student, and this one is so powerful and so inexpensive ($150), that I may just buy it to play around with it…….Dan

The HP 50g graphing calculator offers more connectivity options and greater configurability so users can more easily share their work. The HP 50g is designed for engineering, math and science professionals and students. Connectivity options include industry-standard USB, SD card and serial ports as well as wireless infrared communications.

Users also can customize the calculator by developing and saving programs and macros and by re-assigning key functions so that the most-used functions are at their fingertips.

In addition to the standard Algebraic mode, the HP 50g offers the Reverse Polish Notation (RPN)(2) and groundbreaking Textbook data entry modes that are only found on HP calculators. RPN is an efficient sequence that reduces the number of keystrokes needed to make a calculation; Textbook entry allows users to write and edit equations symbolically, as if they were writing on a sheet of paper.

The HP 50g also offers applications exclusive to HP that simplify working with complex mathematical problems. HP Solve saves users time by writing and solving equations for any variable without having to re-enter or modify the original equation. The HP Equation Library allows for convenient on-board access to more than 300 of the most common equations with pictures. The intelligent editor also allows users to cut, paste and copy objects to isolate and evaluate sub-expressions.

In addition, the calculator includes Computer Algebra System software, which makes it easier to perform complex arithmetic or calculus functions by manipulating mathematical expressions in symbolic form.

Users can expand upon the already-robust 2.5 megabytes of memory through the SD card port, and flash ROM allows for future system upgrades.(3) The HP 50g is permitted for use on some college entrance and professional exams in the United States4) and is backed by HP’s award-winning service and support.

The suggested retail price of the HP 50g is $149, and is available from the HP website and from retailers and bookstores across the United States. For more information, go to the HP 50g web page.
