Tea Vui Huang writes – “The objective here is to create 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. “Link.

  1. If the target is schools, I see a teensy-weensy problem. Any student tech-savy enough to install this on their cell phone should also be more than capable of text messaging their friends while taking the test.

  2. A calculator based on a phone that doesn’t have a large dedicated keyboard to make the calculator more efficient is not going to be all that useful. For most tests, a scientific calculator is sufficient. Having a graphing calculator primarily rewards people who find out how to use their devices to their fullest potential. The majority of students don’t know about functions to find the root and zeroes of a function.
