TVH-72g Graphing Calculator - TVH-72g Graphing Calculator is a low-cost introductory & disposable graphing calculator for the educational use of schools and students who may have difficulty, are unable or may not wish to acquire a stand-alone feature-laden graphing calculator.
The TVH-72g Graphing Calculator is a small 14 Kbytes Mobile Java program that can be installed over-the-air (OTA) or locally via infra-red or data cable from a PC or notebook. For the latter, the student's phone may be equipped with the software using a school computer hosting a copy of the license-free TVH-72g Graphing Calculator. The TVH-72g occupies barely 0.1% of the J300i's 12 Mbyte phone memory; it can also be easily deleted by the student when it's no longer needed.
The keys on mobile phones are generally not arranged in QWERTY format, which fits one of the requirements for using graphing calculators in exams. The TVH-72g has no memory functions and does not use the exam-forbidden Computer Algebra System (CAS). The TVH-72g graphing calculator plots graphs of quadratic equations and trigonometric functions.
Note: TVH-72g Graphing Calculator is free for personal use, educational institutes may freely distribute the software on notifying the author.
