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…]
