Best Graphing Calculator
Some people say that you can complete your standardized exams without a calculator. However, you’re putting yourself at a huge disadvantage. You need a graphing calculator so that you can perform calculations, evaluate expressions, and graph functions with ease.
Without a graphing calculator and you’ll run the risk of failing your exams. On average, standardized exams take at least 2 hours to complete. That’s why you need to invest in a good graphing calculator.
During this time, a graphing calculator will help you solve your problems faster. As a result, you’ll receive a higher score on your exams which will lead into you getting accepted by a higher education institution. We’ll help you find the right graphing calculator to ensure future success on math exams.
When considering which graphing calculator to purchase, there are few things you should know:
In order to get a graphing calculator that’s useful, you need to decide if it’s a CAS or Non CAS calculator. CAS stands for a computer automated system. It’s a software that allows you to manipulate and calculate expressions in symbolic form similar to human computations.
When comparing a CAS and a Non CAS calculator, there’s one thing that sets them both apart. CAS calculators can deal with equations that require symbolic manipulation and prints out a symbolic result (equation). Non CAS calculators deal with the equations in numerical format and prints out a fraction or a decimal a s a result.
A CAS calculator can expand, simplify, and evaluate an equation. The main benefit is that a CAS calculator is able to work with exact forms. While some colleges suggest that students use a CAS calculator, they are better suited for professionals who encounter symbolic expressions often. Here are a few things that CAS calculators can do:
Powerful and faster: It’s faster to find and check solutions to complicated math problems than with pencils and pens that would take longer than usual.
SAT Advantages: Students who are adept at using a CAS calculator tend to perform better on the SAT and saves them more time.
Easier Graphing and Illustration: The input and the calculator display looks similar to the equations you’ll see on paper.
Intuitive: Users with a CAS calculator feel more like a PC and not a assembly language. It takes less time getting used to and you can use it to solve your problems faster.
More likely to be banned: Some college exams don’t accept the use of a CAS calculator during exams. However, the U.S. College Board accepts the use of a CAS and Non CAS calculator for AP and SAT tests.
Can’t show work: If your teacher want your student to show your work, a Non CAS calculator would be more acceptable. CAS Calculators have features and capabilities where a student doesn’t have to show their work at all.
Expensive: With an advanced calculator software, it comes with more fees. Non CAS calculator are less expensive than CAS models.
Some calculators are able to deal with a dynamic range of data. Dynamic properties is defined as a method where users can assign temporary data to certain objects or give data that you want to correlate to an instance of a class but not the full class altogether.
While you might not see them on your exam, its important to find a calculator that can computer and solve dynamic property problems. Most CAS calculators will are useful in this situation as they can quickly assign temporary data and quickly compute the result.
Your graphing calculator should be one that’s easy to read and clearly displays your results. Natural display shows your mathematical computations in a way that they would appear manually.
Natural Display has an advantage when it comes to showing work. Not only does it solves the problem, but it displays the results in a way that appears as if it was done by hand. Thus, you need to invest in a natural display graphing calculator to receive the best results.
With a 3D Graphing calculator, you have more range of control over your graphs in comparison to 2D models. 3D calculators can graph their equations on an x-y-z axis. But, the 2D models are only able to graph on a x and y axis.
You should get a graphing calculator with a 3D Graphing feature. This allows you to show your graphs in a cleaner format and gives you the choice to computer some high end problems. While it will be more expensive, you’ll never have a problem solving graph equations ever again.
On every standardized exam, you’re going to come across a problem that requires you to calculate the slope. With a CAS graphing calculator you can simply place the equation in the window and compute it within seconds.
First find the y-intercept. This will help you find the missing x or y axis of the equation. Once you’ve found the intercept. Plug it in the Y = Mx + B formula. Once completed, your graphing calculator will display the line function on a neatly shaped graph.
Before you buy a graphing calculator, read what you should take a look on:
Your graphing calculator needs to display your results in a clear and readable format. Try to aim for a calculator with a display resolution of 240 x 240 pixels in order to see your answers without issue. Anything lower, and you run the risk of buying a low quality calculator.
Just like the display, the user interface must be accessible and easy to utilize. Higher end devices come with touchpad screens to allow you to manuever through the interface faster than cheaper models.
Luckily, the TI-NSpire CAS is a great example of a calculator that has a great interface and should be considered if you want something that’s easy for beginners to use.
During the exam, you’ll want a calculator that runs fast. The processing speed of your calculator is measured by RAM. We suggest that you get a calculator that has 2 MB of RAM or more to ensure that it responds instantly and can handle multiple math problems at once.
Without memory, you’re calculator is rendered useless. You need memory in order to store expressions, functions, and other mathematical equations in your calculator. Try to get a calculator with a memory of 15 MB or more. This ensures that you can continue your math projects and store your answers for a later problem.
You need to gauge if your calculator is easy to use or not. For this, you’ll need a calculator that has not only a smooth interface, but takes only a few minutes getting used to. We suggest getting the TI-84 because it provides not only simple controls, but has an easy learning curve which is useful when studying for your next math exam.
The battery life an important feature that most buyers tend to overlook. On average, a graphing calculator’s battery tends to run for 8 hours before needing to be recharged. We recommend that you find a graphing calculator that has either a Li-Ion battery or a USB connected port.
How come? Because both options are easily rechargeable and takes only a few hours to bring your calculator’s battery back to 100%. Taking battery life into consideration will not only help you pass your test, but also have a long lasting calculator that’s willing to assist you when taking it.
There are some occasions where your calculator will malfunction. But, some companies such as Texas Instruments provides at least a 2 year warranty to protect you in the event that this occurs. Before buying, make sure you see the warranty of the calculator is at least 1 year or higher.
Why do you need a warranty? Because graphing calculators aren’t cheap and paying an extra $100 or more for a new one sounds like a waste of time and money. Get a warranty to save money and to ensure your calculator won’t break during a standardized test.
The distinction between the two can be vague at first. Scientific calculators can perform complex mathematical computations but is unable to view it in a graph. Graphing calculators are designed with a modern appearance and has the ability to graph functions with no issue.
After students pass the 9th grade, then its time to use graphing calculators. Scientific calculators are less advanced and take less time getting used to. Once you’re more adept with your math skills get a graphing calculator to handle even more complex math problems.
