Architects, engineers, or high school students all need a graphing calculator to complete complex calculations that regular calculators fail to work. Hence, many people want to buy the best graphing calculator to meet their work requirements.
As a mathematical assistant, the graphing calculator provides a set of available functions to help users handle complicated issues such as graph description, calculus, equations, and trigonometry.
The graphing calculators are increasingly more modern to keep up with the complexity of mathematics and specialized professions. However, choosing an appropriate tool is not easy at all.
No worries! Here is your gift. My reviews below summarize valuable information about this advanced product.
What are you waiting for anymore? Let’s go!
What Is Graphing Calculator?
A graphing calculator is a handheld calculator tool designed to plot graphs. It is also able to process complicated equations, variables, and other calculation tasks.
A key point of this calculator is to solve multiple mathematical functions at the same time. Their results are described onto the screen of the device. Therefore, it gives you a visual look, helping you make the right conclusions.
This equipment is constructed with functional buttons, including numbers, notations, functions, and calculus settings. It primarily includes advanced programmable options to solve various problems instead of a regular calculator.
The plotted graphs are more visualizable, and completed algebraic equations are easier. You not only save time to handle but also understand mathematical calculations quickly.
More than a calculator for solving math problems, this calculator is capable of dealing with other academic fields such as biology, chemistry, physics, and finance.
Users often notice essential features of a graphing calculator such as memory, screen size, screen resolution, and preloaded applications.
The Differences Between A Graphing Calculator And A Scientific Calculator
Both of these calculators are capable of performing sophisticated calculations compared to conventional calculators.
A graphing calculator is different from a scientific calculator by advanced functions that it is programmed.
A scientific calculator feature performs hard mathematical issues such as exponential functions, logarithms, trigonometry, and statistics. Furthermore, it supports physics and engineering tasks, not just mathematics.
Calculation results are not merely numbers; they are displayed intuitively by a graph, a model, or an abstract drawing. The copying and pasting values from this task to another task are performed efficiently, thanks to a smart program preloaded.
To store numbers, it should be a graphing calculator. Besides, some of them have the ability of a Wi-Fi connection. In many cases, downloading applications or data helps users complete tasks more efficiently.
A scientific calculator is much cheaper than a graphing calculator. Display screen design and superior computing capabilities are the reasons for this price difference.
User Manual
How To Use A Graphing Calculator?
The best way to use a graphing calculator is to read the instruction thoroughly because each type of calculator has different usage.
Below is a set of notes that you can refer to using your graphing calculator without any hassle.
Firstly, remember to double-check whether the current installation of your calculator is set up for the math problem you want to resolve or not.
Secondly, ensure that you can solve an equation before you want to draw a graph for it.
Thirdly, try to use calculator function keys and shortcuts as much as possible.
Finally, enter the expression properly as you view. A smart graphing calculator will simplify such expression with a programmed order.
How To Charge A Graphing Calculator?
Some of the calculators can be charged when it gets low, but others do not.
Generally, a wall adapter and a USB connectivity cable are the two most popular devices for charging a graphing calculator.
For a wall adapter, just plug in the adapter to charge your calculator as charging other conventional electronic devices at home.
With regards to a USB cable, connect your calculator to a computer with this cable. The first two points of the cable are a USB hub of the computer and the USB port of your calculator.
How To Clean A Graphing Calculator?
To clean a graphing calculator is not hard but needs to be careful.
Notice to shake the calculator gently for removing large pieces of debris or dirt. Use a cotton swab with moderate moisture to clean the screen and keyboard.
When the calculator dries, wipe gently with a cloth. Then, wipe the backside and the cover of the calculator.
Do not let any droplets of water remain on the device.

Key Buying Guide To Select An Advanced Graphing Calculator
This part gives you some valuable notes to consider more thoroughly before choosing a suitable graphing calculator for your work.
Graphing Capabilities
This is the most critical feature of any graphing calculator.
Each calculator is designed to download applications for plotting. Some devices offer 2-D graphics or even 3-D graphs.
Color settings are crucial because they help you see graphs visually. Every calculator has different color modes, so you should check information about the number of colors, quality, and contrast.
Processor
This is a crucial point that decides whether you buy a graphing calculator or not.
This feature controls the working speed and gives the answers to calculations as quickly as possible.
You should consider about the processor if you often attend exams because time-savings is very necessary.
If you use graphing and compute ordinary equations only, an average speed might be acceptable. Remember that the slower speed is, the cheaper graphing calculator is.
Screen Display
There are many factors of this characteristic, such as resolution, color-coded mode, and sizes.
You should choose a high-resolution LCD to see details on the screen more easily. The color mode is highly recommended with minimum 16-bit color and 125 DPI.
The sizes are very varied. It depends on you, but a big-sized screen is preferable.
Battery Life
Not all graphing calculators are rechargeable.
Some of them last up to two weeks for a single charge or even one month. That is so helpful when you use it over time.
Besides, it should be used as a battery type with 4 AAA as accessible.
Notice that some calculators do not have the battery indicator that alerts when it gets low. Please ask suppliers or see information about this point.
