The TI-84 Plus CE graphing calculator is one of the most popular calculators in the world. Find out the important keystrokes you need to know to use the TI-84 Plus, and learn the math functions and constants that the TI-84 Plus CE makes available to you.Get to know the basics of graphing on your TI-84 Plus CE, as well as how to use the calculator’s zoom commands and special menus.

You can find the standard deviation of a data set in two ways with your TI-84 Graphing Calculator. First, have a look at the long lists to calculate the standard deviation from scratch on the TI-84 Graphing Calculator. Then see how to quickly find the standard deviation using one-variable stats. To help your understanding of standard deviation, this video explains what the abbreviations mean and where you can access these variables in your TI-84 Graphing Calculator.

The Ti-84 Plus calculator can handle three decision commands (If, If . . . Then . . . End, and If . . . Then . . . Else . . . End). Here is how to use these commands in a program.The If commandThe structure of the If command appears in the first screen. If the condition following the If command is true, the program executes the command following the If statement (Command 1) and then moves on to the next command in the program (Command 2).

The TI-84 Plus C graphing calculator is one of the most popular calculators in the world. Find out the important keystrokes you need to know to use the TI-84 Plus, and learn the math functions and constants that the TI-84 Plus C makes available to you.Get to know the basics of graphing on your TI-84 Plus C, as well as how to use the calculator’s zoom commands and special menus.

The TI-Nspire device is the most sophisticated handheld graphing calculator available, allowing users to display and evaluate values symbolically, and to reuse the same equations across multiple applications. Because it’s so sophisticated, navigating its features can sometimes be confusing. It helps to know a variety of methods of achieving your aims with the device.

Even the best calculating machine is only as good as its input. This list identifies ten common errors made when using the TI-84 Plus calculator. Wouldn’t it be great to avoid some of the common errors that normally plague students who are using calculators?Using [–] instead of [(-)] to indicate that a number is negative.

On the TI-84 Plus calculator, it's difficult to get a nice viewing window for your sequence on your first attempt. Understanding the basics of sequence notation should help. Here are the variables used in the window of a sequence graph: nMin: Where n starts counting. 1 is the default value. nMax: Where n stops counting.

In the Calculus submenu of the TI-Nspire CAS, the CAS technology allows symbolic manipulation of algebraic expressions as well as numerical calculations just like in the Algebra submenu. The Derivative, Integral, and Limit commands form the cornerstone of the Calculus submenu. Here are some other items contained on the Calculus submenu that are worth mentioning, including a brief description of what they do: Tangent Line (& Normal Line): The syntax for this command is tangentLine(Expression, Variable, point).
