It might also be helpful to check with your teacher or professor to see which calculators are accepted. In the meantime, read on to see the best graphing calculators to buy today.
The TI Plus CE Graphing Calculator comes preloaded with more than a dozen applications such as inequality graphing, correct math notation, and data collection. The thin, lightweight design features a high resolution, full-color backlit display with a sleek design. The graphing calculator also comes in several different colors: black, pink, white, coral, gold, mint, gray, and blue, so you can find one that suits your style.
The full-color screen enhances the display experience, making graphs easier to read by adding color-coded equations, plots, and objects.
The TI Plus CE includes a rechargeable battery that keeps you from having to head to the store to stock up on batteries.
It also means you need to make sure your graphing calculator is fully charged before class and especially before heading out for standardized college testing. An upgrade from Texas Instruments' TI-Nspire CX graphing calculators, this version offers faster performance, interactive visuals, and graphics that are easier to read. In addition to computing basic equations, this graphing calculator can plot functions and equations, construct geometric figures and animations, graphically create a hypothesis, perform calculations on data , and more.
There are six different graph styles and 15 colors to choose from to distinguish each of your graphs. This product comes with a rechargeable battery. The icon-based menu makes it easy for students to navigate. The high-resolution LCD display includes enlarged-dot area technology that enhances the visuals—lines and curves are sharp and easier to see and comprehend. The high-speed CPU processes lengthy calculations and complex graphs quickly and accurately, which is essential during test time when every second counts.

You can navigate the functions by using any of the 15 pre-loaded icon menus. It features the same speedy processing as other models and is even approved for use in college entrance exams and AP tests. The LDC screen features 64 x pixel resolution and offers a clear display.
The built-in memory can store and analyze up to 10 matrices. The TI Plus graphing calculator comes preloaded with essential functions for all your graphing needs. Users can easily access advanced functions by pulling down the display menus.
The calculator features horizontal and vertical split-screen options, allowing users to view the essential information on the screen without having to scroll around. The Texas Instruments Nspire CX CAS graphing calculator features advanced functionality for students taking advanced high school coursework and university students in math, science, and engineering classes. You can even import digital images and place graphs and equations on them.
It's also possible to create documents and pages and store them the way you would with a computer. Even more, you have the ability to enter equations in proper notation—with superscript and subscript. Those taking courses such as Chemistry and Physics will find this functionality helpful since it helps students discover the theory that drives equations.
Students in Pre-Algebra or Algebra 1 or 2 may not find this calculator useful. With a natural textbook display, it has a high-resolution LCD screen with over 65, colors and 82, pixels.
It's useful for high school and college math classes, as well as finance and business purposes. Along with the ability to create 3D graphing designs, this graphing calculator offers Python programming and picture plot technology to display real-life images. It also comes at a great value and is easy to use, thanks to a straightforward icon-based menu.
With a generous 2. Better yet, this graphing calculator comes with a one-year warranty and a USB cable to share files with other calculators or connect with computers. Its advanced features, including a Computer Algebra System CAS to solve most equations, make it ideal for those in engineering or physics fields. The Texas Instruments TI Plus CE view at Amazon is the best overall graphing calculator because of the value it offers: it has an excellent colored back-lit display, is rechargeable, and has the most popular applications preloaded.
They may recommend the best model for your course, and you can also check College Board to see which models are approved for use on SAT and AP exams. Use your course and exam requirements as a guide, but if you plan to continue your mathematics studies, it may be worth going for a more advanced model.
It's important to consider the size and clarity of a calculator's display—some have color screens while others are black and white, and more advanced models display 3D graphs and real images. If you plan to study advanced math and engineering, you may want to choose a calculator that has additional applications such as making spreadsheets, creating documents, or importing images.
Some models can be charged or connected by USB to other devices, while others are typically powered by four AAA batteries or rechargeable batteries. Graphing calculators offer all of the basic calculation options of a regular calculator, along with a display screen that can plot graphs and perform complex equations.
They are different from scientific calculators, which can also handle some complex equations in that they have graphing capabilities. The TI, for instance, keeps 13 digits. Note that this example can be used to illustrate that, to a calculator, addition is not associative.
Now, the result is correct since at no time does the machine need to add two numbers whose magnitudes are vastly different. The problem isn't the magnitude of the numbers involved in the calculation, but rather their relative magnitudes.
When you try to add two numbers of vastly different magnitudes, a and b , you'll have problems. Bizarre effects of round off errors can be illustrated graphically. Graph in a window centered at about 0,2. Then repeatedly zoom in with a horizontal factor of 10 and a vertical factor of 1 thus leaving the vertical scale unchanged.
After about 12 or 15 zooms depending on how many digits of precision your calculator carries , the graph goes haywire. In fact, eventually if you zoom in a couple more times , the result becomes exactly 1. When a calculator without a built-in Computer Algebra System CAS finds a numeric derivative, typically it uses an approximation like.
Note that points on either side of a are sampled, and the slope of the line segment connecting them is returned as an approximation to the slope of the tangent line at a. This approximation is pretty good for most purposes, but can cause trouble for the unwary user. In particular, strange results occur at a place where f' x doesn't exist, or at a place where f x is not continuous. Try these:. This secant line is very steep indeed! Here's an example where the calculator's built-in numerical integration algorithm can be fooled.
CAS-equipped machines do better on this one! The result should be 0. The problem is that the numerical integration algorithm stops taking larger partitions as soon as a few successive approximations agree. The first few approximations give a sum of zero, since the integrand is very close to zero for large values of x.
The root finding algorithm built into the TI-8x will occasionally fail to find even simple roots. The intersect feature simply relies on the numeric solver applied to the difference between the selected functions. The problem in both cases is that the root-finding algorithm is overly dependent at the outset on finding a sign change for the function.
