The Complete Guide to Graphic Calculators

Graphic calculators are a type of specialised calculator that have the ability to perform advanced requests, such as plotting complex graphs and solving multiple equations.

Graphic calculators are popular with engineers, physicists, mathematicians and other professionals working in a field that requires them to use an advanced calculator over conventional types, such as the handheld or pocket calculator.

There is an extensive range of graphic calculators for sale on the current market to suit the difference in individual requirements, preferences and tastes.

The purpose of this guide is to inform the reader all about graphic calculators, and to explain how to purchase them safely and efficiently from eBay.

Graphic Calculators

Graphic calculators (also known as ‘graphics calculators’ or ‘graphing calculators’) are a type of handheld scientific calculator that can perform complex functions from plotting graphs and charts to solving simultaneous equations and working with variables.

Renowned electronics manufacturer, Casio produced the first example of the graphic calculator in 1985. The calculator was very advanced for its time, as it offered 82 scientific functions and was capable of manual computation for basic arithmetic problems.

Examples of the extensive range of complex tasks and functions that graphic calculators can perform include (but are not limited to):

· Angle measurements

· Bar charts

· Complex numbers

· Distribution tests

· Dynamic graphing

· Fractions

· Graphing

· Logic operations

· Pie charts

· Roots and powers

· Single and double variables

· Statistical and financial calculations

A Graphic calculator hosts a screen that is larger than most conventional calculators. This larger screen allows several calculations or multiple lines of text to be viewed at the same time.

Some modern graphic calculators are capable of colour output and can also feature animated and interactive drawings of math plots in 2D and 3D. Many of these graphic calculators also permit other figures like animated geometry theorems and the preparation of documents, including plots, graphs, drawings, and so on.

Besides engineers, physicists and other working professionals, this type of calculator is suitable for children attending secondary school children, although they might not be required at this age in most education systems.

Other Common Graphic Calculator Uses

Besides their conventional mathematic and statistical uses, many graphic calculators can also be used in conjunction with other electronic devices to enhance children’s learning of maths, statistics and mechanics (engineering).

The electronic devices that can be used with graphic calculators include: electronic thermometers, weather instruments, light and decibel meters, pH gauges, and accelerometers to name only a few. Graphic calculators may also be used in a similar way with Wi-Fi for polling, monitoring or interacting with the teacher.

Most graphic calculators are also programmable, which allows the user to create customised programs. Due to this, many graphic calculators are used for gaming purposes, with a large body of user-created game software on most popular platforms. Graphic calculators are extremely popular with those who enjoy maths-based games, as they provide a superior math programming capability that isn’t generally found in other handheld gaming devices.

CAS Calculators

CAS calculators (also known as ‘symbolic calculators’) are specialised forms of graphic calculators that are capable of producing a symbolic result typically using a Computer Algebra System (CAS). The symbolic result is often displayed in equation or expression form on these calculator types.

These calculators can essentially solve X and Y equations taking a lot of the work out of the user’s hands and mind; this is why CAS calculators are often forbidden for use in many mathematics, science and engineering exams.

New and Used Calculators

Graphic calculators are specialised gadgets, and as such can be quite costly when bought brand new. That’s why it is often a good idea to consider purchasing a used (second hand) calculator to save money.

Another key advantage of purchasing a used graphic calculator rather than a brand new one is the knowledge that the product is of good quality, because someone has already used it and it is still in a suitable condition to be re-sold for another owner to use and enjoy for many years to come.

Also, opting to purchase a used graphic calculator over a brand new one is also a form of recycling and is therefore a more environmentally friendly option than buying brand new.

How to Buy a Graphic Calculator on eBay

The choice of graphic calculators online greatly outnumbers those that can be found on the high street, and numerous amounts can be analysed and compared next to each other, aligned with the buyer’s individual requirements and preferences. In this sense, eBay is ideal for presenting a quick, easy and effortless option when searching for graphic calculators on the Internet.

For the most successful purchase on eBay, please use the following advice for efficient and safe shopping on the website:

  • Search: In order to start a search on the website, enter ‘graphic calculator’ into the search toolbar. Then, using the menu located on the left-hand side of the screen, select ‘Electronics’ followed by the subcategory ‘Calculators’.
  • Brand: Some people may have a preference over the manufacturer or brand of the product when it comes to electronic goods. If this is the case, eBay stocks a wealthy range of calculators produced by highly reputable electronics manufacturers, such as Casio, Hewlett Packard, Sharp, Texas Instruments, and many, many more.
  • Shop Safely: To ensure the most successful purchase on eBay, always read the product description thoroughly (to confirm exactly what is being purchased), and review the postage details and payment options prior to purchase. And remember to contact the seller if unsure about any part of the transaction. This function can also be used to ‘ask the seller’ a question about the product or if more information about the product is needed, so one can come to a decision about purchasing.
  • New or Used: eBay stocks both new and used (second hand) graphic calculators. When searching on the website, tick either ‘new’ or ‘used’ under the category ‘condition’, from the menu located on the left-hand side of the screen.
  • Use PayPal: PayPal is one of the safest ways to pay for products online, as it allows buyers to make payments quickly and safely online using a credit card, debit card or bank account.

For more information about how eBay and PayPal work together to keep customers safe and secure whilst shopping on the website, please visit the ‘About PayPal’ page on the website.
  • eBay Deals: Don’t forget to check out the latest deals on calculators by looking in the ‘Electronics’ section. Many fantastic additional discounts can be found here along with free postage costs.

Conclusion

There are many issues to consider and factors to take into account when purchasing a graphic calculator. However, with the important information and careful considerations outlined within this guide, coupled with eBay’s highly detailed and user friendly website, buying a used calculator can be quick, easy, and painless.

Buying on eBay should be considered not only due to the potential of finding a good deal, but due to the extensive choice of graphics calculators that the website presents. Remember to always keep all personal information and banking details safe and secure by using payment authority PayPal to complete transactions with eBay sellers.
