A graphing calculator is an indispensable tool for college students who are specializing in mathematics, statistics, or physics. If you also fall into this category, then you can evaluate the purchase of a product of this type, perhaps in its printed version, or that equipped with a large display to view formulas, diagrams, etc.
Below you will find our buying guide in which we have highlighted which aspects you will need to consider before choosing the model that best meets your needs. Below you will also find the ranking with those that are for us the best models on the market for the relationship between quality and price.
Here we had listed out the best quality of hp prime graphing calculators that are present below.
Hp Prime Graphing Calculators Buying Guide
Wealth of Features
Although aesthetically the graphing calculators recall the traditional ones, since some models produced by the best brands can contain dimensions and dimensions, they boast a very high number of functionalities that make them versatile and extremely useful for performing even very complex operations.
For example, let’s talk about the ability to solve equations of all kinds, derivatives, complex functions, statistical calculations, and, in the case of graphical models, the possibility of managing tables, Cartesian coordinate systems, and much more.
There is also the option to switch from one numerical system to another: from the decimal to the binary, from the octal to the hexadecimal system. It is good to read reviews and data sheets carefully to be sure to choose the model that includes the operations you will find yourself performing most frequently.
These calculators are sophisticated tools that, in a sense, can be equated to a small computer for the integration of a chip that takes care of all these calculations.
And the ability to communicate with a PC, connecting via an ad hoc cable to the USB input, to share files, applications, and calculations, represents an additional added value.
Large Screen
If, in the models of traditional scientific calculators, the size of the screen matters but up to a certain point, in the graphic ones, they represent one of the fundamental choice points.
A large display, which supports a large number of colours, is, in fact, a guarantee of quality and viewing comfort, especially when you find yourself viewing histograms, pie charts, or box plots.
The comparison between the prices of the various devices highlights just how the screen represents one of the aspects that most affect the final cost. In case you are willing to spend something more, our advice is to opt for a colour calculator, with a display with a good resolution.
If, on the other hand, you want to save money, you can go to a black and white product. The aspect on which you can not skimp, however, is the size of the screen, so as not to strain your eyes too much in an attempt to interpret the results obtained.
Ease of Use
The computing power that these calculators need comes from the integrated processor, which, of course, must be powered by an energy source. Contrary to the simpler and academic models, which can be “supplied” even by a small solar panel.
The graphic ones need the power supply of the batteries, typically the stylus ones. Being a portable device, it is rather easy to speculate that you will often have it with you, at university, or wherever you go to study.
It is, therefore, important to opt for a model that combines a wealth of functions (which also passes through a full keyboard), the size of the display, and the compactness of the body. This way, you can easily keep the calculator in your jacket pocket or store it without excessive hassle in your backpack or bag.
How to Use a Graphing Calculator?
Mathematics is often a nightmare for students. Yet if you stop to think for a moment, the world of numbers, of logic, is fascinating. Do you think this science is part of our daily life, from the most trivial calculations to the most complex operations?
In short, we do math even when we don’t realize it. But math does not just number but also graphical representation, and some calculators show graphs on display.
Who Is Cas for And What Is It For?
The graphing calculator is extremely useful for students of scientific high school but even more for university students of mathematical sciences and engineering where things get more complicated.
Speaking of high school students, the good news is that unlike in the past, graphic calculators are now admitted to high school exams but with a stake: the device does not have to be equipped with the CAS function.
The question arises: what is the CAS function? The Computer Algebra System develops and shows all the steps that led to obtaining the result. Using this function is equivalent to copying.
Functions
One of the most important elements for a scientific calculator or, to be more precise and relevant to the object of our article, graphics, are the functions. In the previous paragraph, we specified how the CAS is not allowed to take the math test during high school exams. Still, it seems obvious to us that the greater the functions available, the more interesting the calculator proves.
It seems natural to us that if you are an engineer or a student at a scientific faculty, it is in your interest that the calculator has all or almost all of the existing functions.
The Graph
If the choice falls on a graphing calculator, it is because it is, in particular, this function that interests us. Then we have to take into consideration the display which must be large but not at the price of becoming bulky, well legible and illuminated. Choose a calculator whose display is also appreciated for its range of colours.
Interaction with The Computer
Another feature that we consider of great importance, especially for professionals, is the possibility of making the calculator interact with a computer. In this way, calculations and graphs can, for example, be transferred to the computer.
Comfort
Many keys and many functions can result in inconvenient use of the calculator. It should be checked whether pressing the keys is an immediate operation or if there is the risk of pressing one button for another because it is too small and close to the others. A calculator in such conditions is inconvenient.
