Whether you’re a student, have a budding mathematician in your life or work in a job requiring complex graphing and computations, you likely know that a graphing calculator is a handy device. From checking your work to comparing different theoretical scenarios, graphing calculators are just as relevant today as they were when they were first introduced back in the mid-1980s.
While the style and look of a graphing calculator haven’t changed since their inception more than three decades ago, for the most part, neither has math. Graphing calculators remain a staple for advanced math classes and on the desks of professionals in several fields, including engineering and finance (also check out the best financial calculators). In addition to general graph plotting, a graphing calculator can help with everything from algebra to trigonometry.
And though computers, tablets, smartphones and the best scientific calculators can be used to address fundamental math problems, graphing calculators continue to help teach and aid those working on more technical issues that are best viewed on screen.
What To Consider Before Buying a Graphing Calculator
Your best graphing calculator will depend on your specific needs and circumstances. Here are several questions to ask yourself before choosing from our selection of devices.
Are there any restrictions on what calculator you can use/own? If you’re a professional looking for a graphing calculator, you can choose any model as there are no restrictions. However, all students should make sure any selected calculator is suitable functionally and, more importantly, allowed in your classroom/exam. The majority of graphing calculators indicate what exams they have been approved for. But it’s always a good idea to double-check with proctors and teachers before any test day comes around.
How advanced do you need the calculator to be? Remember that the most advanced and complicated calculator isn’t always the best one for every need. A graphing calculator beyond the scope of your class or profession may give you more headaches and create more confusion than it solves. One big consideration is whether you want CAS (Computer Algebra System), which allows you to manipulate expressions in symbolic form rather than just numerically.
Do you prefer battery-powered or rechargeable devices? Look at the power source for the calculator. If you’re good at remembering to plug in their devices, a rechargeable USB calculator may be a better fit for you. Otherwise, opt for a battery-powered calculator and pack a backup battery in your backpack.
Do you want to be able to create color graphs? If you find it easier or more pleasing to see graphs presented using color over black and white, ensure you opt for a device with a color screen.
