Buying Guide: What to Look When Select Graphing Calculator
Seeking out the best graphing calculator among the vast variety of options on the market can be a little daunting. That is if you are not sure what you really need a calculator for. Clearly, you would need to have an idea of what you are going to do with the calculator in the first place. Once you have cleared this up, your choices will be easier to make.
If your purpose is to use a calculator in school for science or mathematics, then the recommendation is for you to stick to the scientific calculator. The scientific calculator is quite suitable and sufficient for school and some college courses.
For students pursuing higher level mathematics and science courses that require a more robust instrument, then the graphing calculator is more suitable.
So, let us take a quick look at what you need to consider when choosing your calculator.
Is it allowed for your course?
Check with your course requirements carefully to ensure that the graphing calculator you are looking at is indeed what you need for your program. Also, check the tests you will be taking to ensure that your graphing calculator is allowed or approved for such tests. If not, you may need to consider a different type of calculator.
Does it have enough functions?
The answer to this question is important in your choice of the most appropriate graphing calculator. The more functions it is able to carry out, the more versatile the instrument is for your purposes. In looking at the calculator’s functional capabilities, also check whether it can deal with 2nd, and 3rd level functions and higher functions as well.
What can it graph?
Obviously, a graphing calculator should have the capability to produce graphs. But, how many functions can the calculator graph? There are numerous formulas, functions, and expressions that can be graphed with a decent graphing calculator. Check the brand and test what it can graph.
Some brands are designed with the student in mind so the graphs produced are mainly algebraic or based on calculus. For the business or professional user, some brands offer high end functions to produce graphs based on data that is put in as well as statistical information.
Does it allow for download of apps?
Some brands of graphing calculators have the capability for users to download apps and programs to enhance its built-in functions. With so many useful apps and programs, you have a range of possibilities to boost the capacity of your graphing calculator.
With this ability, you can produce far more graphs and solve a range of problems than if you were to use any other kind of calculator.
How much will it cost?
OK, so the cost question may be relevant to quite a few of you. It is already clear that a decent graphing calculator will dig deep into your budget. If you can stand it, then buying the most feature rich graphing calculator is not a hard decision to make. If cost is, however, a consideration, then shop around for the best option you can afford.
What is a Graphing Calculator?
Graphing calculators are designed to present graphs that have been plotted based on complicated equations like parabolas. These calculators are more sophisticated tools that help to process various equations and perform complex calculations. You will see the results as a graph on screen rather than calculated numbers.
Unlike the basic calculator you might have used at school, the graphing calculator also deals with additional items like tangent, sine, and cosine. A graphing calculator is more commonly used for high-level maths like calculus, algebra, and trigonometry so they are not really made for lower-level, basic maths for which an ordinary calculator is more appropriate.
CAS vs. non-CAS Graphing Calculators
First off, CAS stands for Computer Algebra System which is designed to manipulate mathematical expressions to produce a result. How do you know whether your calculator is CAS or non-CAS? You can tell by the kind of results they generate.
So, for example, a CAS calculator will produce responses such as a simplified equation, factors, and indefinite integrals that include their symbols exactly as they would appear on paper!
A non-CAS calculator, on the other hand, will produce numeric answers, whether in decimal, radical or fractional form. Another thing to note is that a CAS calculator is not always allowed in certain exams, especially where the student is asked to show their work (how they arrived at the answer).
This is to allow the student to actually show how they arrived at their answer rather than depend on the automatically generated response provided by their calculator. The non-CAS calculator, on the other hand, is more basic and does not have the capacity to produce algebraic and other symbolic results.
Scientific vs Graphing Calculator
Here are a few things that differentiate the graphing calculator and the scientific instrument:
How they function: Unlike the scientific calculator, the graphing calculator presents a graph after you type in the mathematical function and solves complicated formula.
The size of the screen: The screen of the graphing calculator is larger to allow users to see the graphs produced.
The cost: The graphing calculator is much more costly owing to their more advanced (and complicated) features.
The advanced features: Graphing calculators have more advanced features and are mostly used for advanced mathematics and by professionals like architects, engineers, and designers.
Wi-Fi capabilities: Unlike scientific calculators, graphing calculators are compatible with Wi-Fi to allow data from other devices like meteorological gauges to be accessed.
How to Use Graphing Calculator
If you have a graphing calculator and are not sure how to make the best use of it, we have a few tips for you. As you may realize by now, the graphing calculator is quite useful for high-level maths and for certain professionals who rely on graphical displays of mathematical information. So, it is good to be able to use your calculator to its full potential.
If you are a student in college or university who are allowed to use graphing calculators in tests or exams, you would still need to show your work. You may, therefore, do the work manually and use the graphing calculator to recheck what you did.
In any event, here are some things you need to ensure when using a graphing calculator.
Ensure that your calculator’s mode is set based on the problem you are solving. Check for the mode button and set your calculator. You can make changes such as radians or degrees.
So, if you are working in degrees, ensure that you set the calculator to that mode before you enter the problem you want to solve. Some graphing calculators allow you to choose among ten different modes.
Another important thing is to make sure that you are able to solve for y before attempting to plot a graph. You are able to plot almost any graph using the graphing calculator once you have solved for y. Graphing calculations are designed to accommodate equations that are solved for y.
Know the shortcut menus that are available to you and utilize as many of the functions of the calculator as you can. Most graphing calculators also have shortcuts to other concepts in maths. Examples of this is finding the root of numbers, entering matrices, and changing a decimal.
Things might be a little different depending on the brand of graphing calculator that may be one of a kind. With shortcuts, you can be better able to work quickly without having to enter the mathematical expression every time. You will also be able to quickly check your work.
Enter the expression in the same way it looks on paper and the graphing calculator will handle the rest. This includes simplifying the equation. Note that a few brands of graphing calculators have the math shortcuts built-in. which is great as they automatically start by grouping parentheses.
Some steps you would need to take to produce graphs on a graphing calculator are:
- Press the y= button to bring up the editor for graph equations
- Enter the function key then press “trace”. The graph will fully load after a few seconds. Be aware that the graph equation editor allows expressions in the form of y=f(x) when you are working with functions.
- Press the second then calculate keys. Find the operation you are trying to use. If it is a derivative then the function would be dy/dx but if it is an integral then the function would be (integrand) f(x) dx
- Set the point you want to differentiate at. Depending on the function you have selected, you may also enter the lower then upper limits. A bar will appear at the bottom of the screen with your entries that you would need to confirm before they are graphed.
The graphing calculator usually comes with instructions from the manufacturer that will help you learn how to fully use the instrument. You may also go online for great tutorials on how to use the graphing calculator.
