# Texas Instruments Ti-83 – Mathematics made simple

A calculator is perhaps the most essential tool for a student taking mathematics as a subject and is a must have device to help in studies. There are various types of calculators for professionals and students of different fields. These range from simple ones with minimal functions to complex scientific calculators and graphing calculators which are more popular among the students. As today’s technology is advancing at an ever increasing pace this has resulted in the development of better, faster calculators by increasing their computing power, adding more functions in them. Now complex mathematical and lengthy statistical formulas can be solved in no time with modern calculators.

The latest and most incredible development in calculators is the graphing calculator and online graphing calculator ti-83. A graphing calculator can be extremely useful in many ways. They are used to do mathematics of different kind. The main point that attracted the attention of buyers is that these are capable of solving the most complex functions that cannot be done by any other calculator.Whatever is the length of numbers in a calculation, graphing calculator can be trusted upon unquestionably. Most importantly these calculators can draw lines and graphs upon the insertion of right data and coordinates by the user. They also contain normal functions like other calculators and the combination of normal and advanced functions gives the perfect results. They contain all the functions that a normal calculator has. To acquire the basic mathematical answers, all the necessary calculations and complex math formulas as embedded in them. Each time a set of numbers is inserted, the pre-programmed addition, subtraction, multiplication, division, logarithms, square roots, fractions and decimals functions help in getting accurate answers from graphing calculators.

There are currently two types of graphing calculators, hand-held and online emulators. The most notable component of a hand-held graphing calculator which makes it more efficient from other calculators is a mini computer system with the most complicated programming inserted in it. This makes the tasking easier and faster for it. No matter what you are doing, algebra or geometry, this calculator performs them both with greater ease. But it is not over yet, the graphs of these functions can also be drawn on this calculator. The Zilog Z80, most advanced microprocessor in calculating devices, helps calculator in understanding and interpreting the commands efficiently and quickly. Some of the common functions that can be performed with graphing calculators are plotting lines, graphs, matrixes, regression and correlation and logarithms.

The screen size affects the capability to draw a perfect graph. The equation results are spread across the available pixels equally. There is no problem with the small graphs but the big graphs might need to be checked for accuracy by drawing a test graph on calculator and paper and comparing them with each other. You can also have a calculator with bigger screen as there are many models available in the market. The problem can also be resolved by using an online calculator and preferably online graphing calculator ti-83. The screen size restriction is removed inonline emulators and you can have a full sized graph with 100% accurate results.
