A Buyer’s Guide to Choosing a Best Graphing Calculator
Here’s a guide to help you buy the right graph calculator.
What Is a Best Graphing Calculator?
A graphing calculator is a more sophisticated version of a scientific calculator that can not only perform complex mathematical operations, but also visualize the data. The large, clear screen allows users to see graphs and equations, making it an essential tool for students and professionals alike.
These calculators can solve simultaneous equations, plot graphs, find intersection points, and account for different variables. They help the user understand solutions and the effects of variables on these solutions by plotting outcomes visually.
Graphing calculators have a much larger display screen than basic or scientific calculators, making them ideal for viewing graphs and equations. Most scientific and basic calculators only have a 2 or 3-line display, which can make it difficult to see equations and solutions.
The more expensive a graphing calculator is, the more features and benefits it offers. Some high-end features include high display resolution, color graphics, zoom settings, and more.
Graphing calculators are also programmable, which means you can create and store your own programs and functions in their memory. This can help automate your processes and make calculations a lot faster.
Some important factors to consider when buying a graphing calculator include
Here are some important considerations for choosing the best graphing calculator:
The display of the Best Graphing Calculator
Your graphing calculator should have a sufficiently large display to show complete equations and graphs clearly. You should not feel the need to use a magnifying glass to locate X/Y interception or read a number.
The resolution of a screen is a more important consideration than its size. A graphing calculator should have a screen that is at least 2.8 inches. The ideal resolution would be 320 x 240 pixels.
It’s important to remember that a large screen doesn’t mean better graphics. You should be able to see everything in high definition and with clear, vibrant colors to save time and avoid confusion.
The ease of use
In order to work efficiently, you will need a tool that is easy to operate. This means that all of the important functions should be quickly accessible. You can look for some simplified keyboards that have all of the functions grouped together and easy to access.
Additionally, take the colors of the keyboard into account. In general, white on black offers the best and clearest lettering on a calculator. The contrast and combination should be easy to read; you shouldn’t have to squint your eyes to read.
In addition, the home screen and menus should be easy to read and navigate. Having to run through and press multiple buttons to get one solution is not ideal.
Best Graphing Calculator Customization
A graphing calculator is a great investment for any student, as it will be useful for many years to come. It is important to choose a calculator that can be updated and customized as your needs change.
Some high-end calculators also come with the ability to download video games. Others would even allow you to 3D print your own blueprints, taken directly from a website. You can program your calculator to solve complex mathematical problems with just the press of a button.
The Memory of a Best Graphing Calculator
A calculator with the ability to recall programs, formulas, and other data from previous courses and tests can be extremely helpful. You can easily access the archives and get to the formula you want. This feature can be very beneficial if you’re not buying specifically for standardized tests, as it’s not allowed on those.
Speed of a Best Graphing Calculator
It is important to have a fast testing speed, but not for the reasons you may think. We found that when we had to wait several seconds for the graph or solution to load, we became ANXIOUS. Even though we still had plenty of time, the waiting made us feel like we were wasting time.
The pressure of a real test can be intense, especially when watching your peers write down answers instantly. That’s why we recommend using fast calculators for the SAT (Numworks or TI-84+ CE) to help ease the pressure.
The Processor
The speed of the calculator is determined by the processor. The processor speed is measured in megahertz. If you need quick decisions, choose the highest speed for fast processing.
Battery Life
The battery life is an important factor to consider when purchasing a calculator. Even the longest tests can be completed with a calculator that has enough juice. However, it can be annoying if the calculator dies after only 3 hours. Every model on this list has been tested to ensure a long battery life.
Types of Graphing Calculators
There are two main types of graphing calculators:
CAS calculators
CAS calculators are efficient because they solve algebraic equations symbolically rather than assigning numerical code to each variable. This makes them much faster than other types of calculators, and ideal for complex calculations that involve many unknown variables.
CAS graphing calculators can be used to solve equations, variables, and factors. They can also be used to resolve expressions and find the min., max, and zero of any function. However, due to their extensive function capabilities, CAS calculators are sometimes not allowed during standardized exams.
Non-CAS calculators
Non-CAS graphing calculators can perform the fractional and decimal functions needed by an average math or science student. And since fractional and decimal results come from numerical equations, these calculators are allowed for use during standardized exams and testing.
Difference Between a Scientific Calculator and a Graphing Calculator?
Both of these variations have more advanced functions than a basic calculator, and they differ in the functions they can perform.
A scientific calculator is able to perform various types of calculations, including those involving trigonometry functions, their inverses, exponentiation, and logarithms. This makes them ideal for students taking math classes at the high school level.
A graphing calculator is designed for more complex functions like calculus, while a scientific calculator is designed for more basic functions. Graphing calculators have a larger screen than scientific calculators, making them more intuitive to use.
The calculator’s memory can also be used to retrieve similar data and functions. Scientific calculators are commonly used by high school students and professors for basic mathematics, while graphing calculators have a more advanced user base. They are used in statistics, engineering, physics, and some areas of mathematics where calculations are more complex.
Some graphing calculators come equipped with Wi-Fi capabilities. This allows users to download games, programs, apps, and data from the internet to help solve a given problem.
For a more clear distinction, if you are working with large numbers, various steps, large decimal values, etc., you would need a smart calculator that can store numbers and display them all at once. Additionally, graphing calculators tend to be more expensive than scientific calculators.
FAQs
