Engineering students use computer graphing calculator for carrying out simple statistics. It is a combination of scientific calculator and graphing device. The gadget is appropriate for its use in typing. The calculator carries all display features from Nokia LCD and sample of Mega 32 code.

Coding computer graphing calculator was carried out with search engines providing the answers. The device contains all basic calculation steps. Input of calculation functions helped in dealing with points on the graph. The calculator has been readied with number of equations.  The features it lacks are zooming and scaling. The whole device has been programmed and coded with C language.

Computer graphing calculator hardware supports keyboard with text, math symbols and numbers. There is STK-500 to help out with Mega 32 Microcontroller.

There is a new version in the market. This has been launched by company called Casio. Its LCD is 3.7”.  It gives texts and equations on the screen at the same time. PRIZM is allowed inside the examination halls. Another great quality of this graphing calculator is its low consumption of electricity. 4 AAA batteries can be used for 140 hrs for using the device.

Ti-89 graphing calculator is for high level maths, it has flash technology. One can add more software to it as required. It is used for AP Statistics, AP Calculus, AP Chemistry, PSAT and NMSQT.

Titanium Graphing Calculator supports USB internet provision.

Texas Graphing Calculator has memory up to 32 KB. It helps maths and science students of middle grade.

GraphCalc is available to download; it only takes up 349K in a zip file. It can do permutations, and also can be used for Combinations. It is free for everyone.

Graphing Calculators performs many tasks with variables. Graphing calculators are compatible with electronic thermometers, weather instruments, light meters, pH gauges, decibel, accelerometers etc. They are good data loggers.

Internet has guidelines regarding any problem that occurs in connecting T1 graphing device and the computer.

There are many graphing calculators which engineering students can opt for. HP 50g has slot for SD card which allows for more memory. Laplace soles many engineering problems, Fourier helps in getting factorial value for numbers other than non integers. One can search among them on the online stores.
