There is much debate about the best online graphing calculator.

A graphing calculator (online or handheld) is a calculator that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables.

For answers, we went to is the simplest and best. Use Plotter if you need a little more functionality.”

“If you want to plot raw data and not an equation, check out .” is pretty good.”

‘Check out ( a free online tool that we made and that can graph equations, solve matrices and much more)’

And, from Math.StackExchange:

“Some good options:”


“I really like Geogebra as a web based graphing tool (requires Java).”

And, finally, there’s and

A Brief History of Handheld and Online Graphing Calculators

For a history of graphing calculators in general, we consulted (who else?) WikiPedia. Here’s what they say:


Casio produced the first commercially available graphing calculator, the fx-7000G, in 1985. Casio’s innovations include an icon menu for easy access to functions (1994, FX-7700GE and later), graphing in several colors (1995, CFX-9800G), expandable memory (FX-9860SD), textbook-like input and output (2009, FX-9750GII & 9860GII), backlit screen (2009, FX-9860 Slim & GII), full-color, high resolution backlit screen (2010, FX-CG10/CG20 PRIZM).


Sharp produced its first graphing calculator, the EL-5200, in 1986. Since then Sharp’s innovations include models with a touchscreen (EL9600 series), Equation Editor (textbook-like input) (EL-9450 and later), and reversible keyboard to ease learning (one side has basic functions, the other side has additional functions) (EL-9900).

Hewlett Packard

Hewlett Packard followed in the form of the HP-28C. This was followed by the HP-28S (1988), HP-48SX (1990), HP-48S(1991), and many other models. Models like the HP 50g (2006) or the HP Prime (2013) feature a computer algebra system(CAS) capable of manipulating symbolic expressions and analytic solving. An unusual and powerful CAS “calculator” is the now obsolete year 2001 Casio Cassiopeia A-10 and A-11 (flip top) stylus-operated PDAs, which ran the Maple V symbolic engine. The HP-28 and -48 ranges were primarily meant for the professional science/engineering markets; the HP-38/39/40 were sold in the high school/college educational market; while the HP-49 series cater to both educational and professional customers of all levels. The HP series of graphing calculators is best known for its Reverse Polish notation (RPN) / Reverse Polish Lisp (RPL) interface, although the HP-49G introduced a standard expression entry interface as well.

Texas Instruments

Texas Instruments has produced graphing calculators since 1990, the oldest of which was the TI-81. Some of the newer calculators are similar, with the addition of more memory, faster processors, and USB connection such as the TI-82, TI-83 series, and TI-84 series. Other models, designed to be appropriate for students 10–14 years of age, are the TI-80 and TI-73. Other TI graphing calculators have been designed to be appropriate for calculus, namely the TI-85, TI-86, TI-89 series, and TI-92 series (TI-92, TI-92 Plus, and Voyage 200). TI offers a CAS on the TI-89, TI-Nspire CAS and TI-92 series of calculators. TI calculators are targeted specifically to the educational market, but are also widely available to the general public. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to (, or,,, or
