### Graph a Step Function in TI-Nspire Graphs Application

Many functions can be graphed by accessing commands commonly used in the TI-Nspire Calculator application. The *greatest integer function**,* *y* = int(*x*), is one such graph, which you create by following these [more…]

### How to Graph Functions on the TI-Nspire

Functionality built into TI-Nspire enables you to graph and analyze functions, inequalities, parametric equations, polar equations, dynamic sequences, phase plots, differential equations, piecewise functions [more…]

### Move from and Hide Entry Lines on TI-Nspire Graphs

You can move to the work area or hide the entry line on a graph you have created on the TI-Nspire. After you press **[ENTER]**to graph an equation, a movable cursor appears in the work area and the entry line [more…]

### Manually Adjust Window Settings When Graphing

The window settings clearly do not effectively reveal the graph on the TI-Nspire. The *x*-values of the function represent the width of the rectangle, and the [more…]

### Use Zoom Tools to Set Your Window on Graphs Page

On the TI-Nspire, it is sometimes easier to automatically set your window on a Graphs page. There are eight different automatic zoom tools. To access the zoom tools, press [more…]

### Manually Adjust Scale on TI-Nspire Graphs Page

You can manually adjust the scale on the TI-Nspire Graphs page. By default, the axes tic labels are shown on the coordinate plane in close proximity to the origin. These can be accessed by pressing [more…]

### Change Your TI-Nspire Graph’s Attributes and Color

TI-Nspire gives you the option of changing your graph’s line weight (thin, medium, thick), line style (continuous, dotted, dashed), label style, and whether the graph is continuous or discrete. Press [more…]

### Use the Trace Tool to Analyze Your TI-Nspire Graph

You have the option of using the Trace tool to perform an analysis on your TI-Nspire graph. First, change the function on the Graphs page to *f1*(*x*) = (*x* [more…]

### Use the Analyze Graph Tool to Analyze Your TI-Nspire Graph

Another way of detecting points of interest on a TI-Nspire Graphs page is to use the Analyze Graph tool. Use the tool to find a local maximum by pressing [more…]

### Use an Alternative Method to Graph a Function on TI-Nspire

You can use an alternative method to graph a function on the TI-Nspire. Before doing so, insert a new Graphs page by pressing **[DOC]**→Insert→Graph or press [more…]

### Perform Calculations on TI-Nspire Graphs Page

Virtually any number that appears on your TI-Nspire Graphs page is eligible to be part of a calculation, including the coordinates of graphed points. You can find the slope of the function by calculating [more…]

### Use the Point On Tool to Analyze Your TI-Nspire Graph

Some of the more common analyses that are performed on a graphed function on the TI-Nspire include evaluation, finding local maximum and minimum values, and locating zeros. The Point On tool offers a convenient [more…]

### Geometric Objects in the TI-Nspire Graphs Application

TI-Nspire gives you the option of adding geometric objects (points, perpendicular lines, circles, polygons, and so on) to your Graphs page. These objects can add some type of functionality to your graph [more…]

### How to Graph Antiderivatives on the TI-Nspire

A function has an infinite number of antiderivatives. In the example given here, you look at a particular antiderivative on the TI-Nspire and then see how to use a slider to investigate an entire family [more…]

### Use the Measurement Tool for Your TI-Nspire Graphs

After you have found the slope of a function, you can use the TI-Nspire Measurement tool to enhance a slope problem. Before you try this, you might need to clean up your screen. [more…]

### Add a Tangent Line to a Graph on TI-Nspire

The Tangent Line tool is a great option for exploring the instantaneous rate of change of a nonlinear function. Start with a fresh Graphs page and graph the equation [more…]

### How to Use the TI-Nspire Measurement Transfer Tools

The TI-Nspire Measurement Transfer tools allow you to transfer the result of a calculation, a numeric text value, or a measurement to a circle, ray, or vector. You can also use this tool to transfer a [more…]

### Use the TI-Nspire Locus Tool and Geometry Trace

The TI-Nspire Locus tool and Geometry Trace provide two options for “seeing” an entire function given by the path of a point (*x*,*y*) as the point on the [more…]

### Add a Function Table to a TI-Nspire Graph

To add a function table to a TI-Nspire graph, press **[MENU]**→View→Show Table. This action automatically splits the screen and adds a Lists & Spreadsheet application with, by default, [more…]
