How to Graph Differential Equations on TI-Nspire

Graphing differential equations is new feature on TI-Nspire. You can set the initial condition(s), customize the slope field, and choose your solution method [more…]

3D Graphing on the TI-Nspire

Graphing in 3D on the TI-Nspire helps students to visualize what a function would look like in 3D (and you don’t need to wear uncomfortable glasses to see it). 3D Graphing allows you to enter an expression [more…]

How to Graph Piecewise Functions on the TI-Nspire

Press [MENU]→Graph Type→Function to switch to function graphing mode on the TI-Nspire. Alternatively, move to the entry line and press [CTRL][MENU]→Function. Two different piecewise function templates [more…]

How to Graph Derivatives on TI-Nspire

The study of calculus should include a focus on the four key mathematical representations: algebraic, geometric, numeric, and verbal. The TI-Nspire Graphs application stands ready to take care of the geometric [more…]

How to Insert a Graphics Page for a Scatter Plot

After you have entered data to construct a scatter plot, you can inspect the scatter plot in the Graphs application of the TI-Nspire. Here’s what you do: [more…]

How to Perform a Cubic Regression

If a cubic polynomial is a good fit for the data on a scatter plot, you need to perform a cubic regression. You can do this in the TI-Nspire Lists & Spreadsheets application. To perform a regression, follow [more…]

Results of a Regression on the TI-Nspire

A variety of variables (26 in all) are stored by TI-Nspire after a regression. To view this list, add a Calculator page and press [VAR]. Using the [more…]

How to Graph and Update a Regression Equation

You can view the graph of a regression equation on the TI-Nspire Graphs page and even change the data and have the TI-Nspire update the equation automatically. To view the graph of your regression equation [more…]

How to Perform a Second Regression on the Same Data

Assume that you have used a set of data on the TI-Nspire to create a scatter plot and perform a regression. Perhaps you want to construct a second scatter plot and associated regression on the TI-Nspire [more…]

Scatter Plots in Graphs versus Data & Statistics on TI-Nspire

You may wonder why you would ever use the TI-Nspire Graphs application to graph and analyze two-variable data. Here are two reasons why you may choose to use the Graphs application over the Data & Statistics [more…]

Summary Plot with Two-Variable Data

One interesting feature of the TI-Nspire is that categorical data can be represented with a summary plot. A summary plot is an excellent way to compare two data sets side by side. A group of students were [more…]
