Thank you for your patience and persistence!
A tremendous feature of the TI-Nspire Calculator is the ability to upload documents and jpeg files to the Handheld unit. The following tasks will show how to convert images from jpg to .tns format, outline a photo with a mathematical function, and how the handheld and your computer interact using the TI software.
21) Installing the TI-Nspire software
TASK 21: Download and install the TI software; Download the .pdf handbook
Go to the Texas Instruments Software download page.
Follow the steps, selecting the appropriate software.Then, download the relevant guidebook.
Then, to install and open, you will need your USB cable and the Software license number you received with the unit.
22) Working with images and folders
TASK: Move jpeg file into the nspire image folder
(plug handheld unit into computer with USB cable)
Open the software (from menu or a shortcut on your desktop)
Find nspire folder on your hard drive
Move jpeg file into the folder (i.e. copy/cut & paste or drag & drop)
NOTE: The .jpg file appears in the "Computer" TI-nspire window
23) Coverting .jpg to .tns files
TASK: Transfer a jpeg file from your computer to the TI-nspire cas cax calculator
**Important: since the unit will not transfer .jpg extensions, you must convert and save the image in .tns form
METHOD 1: "Save to Handheld"
"File" "New Ti-Nspire document"
In the documents toolbox, look at the list from computer images. (select the image)
It appears on the workspace (on your computer)
"Save As" (choose a name)
"Oscar going to nspire handheld" (.tns)
(** Important; .tns file is different than .tnsp file)
"File" "Save to handheld"
(highlight your handheld; doubleclick to enable the save option)
"Save" (the image is sent)
On your calculator, press (OK)
The image is now in the "2 My documents" folder!
To view the new image:
On your handheld calculator,
2: My Documents
In the documents list, select the name using the keypad/cursor to highlight.
The photo appears on the screen!
(Calculator Screen Image)
METHOD 2: Drag and Drop
(From the software platform)
"File" "New Ti-Inspire document"
Insert "geometry" Insert "image"
Select jpeg image (bridge.jpg) open
(the bridge appears in the workspace!)
"File" "save as" "drag and drop bridge" (again, choose files of type *.tns)
The new drag and drop bridge.tns will appear in the computer images folder.
Then, to transfer to handheld:
In the toolbox, select the .tns file
Then, drag and drop it from the "computer" window down to the "handheld" window
The drag and drop bridge.tns file is now in the "2 my documents" folder on the handheld!
(Drag and drop document -- calculator screen view):
24) Tracing images with math functions
TASK: Trace the bridge from task 23 with a quadratic function
On the handheld, "2 my documents"
select "drag and drop bridge" from list of documents
enter (bridge photo appears)
2: view 1: graphing
x/y coordinate graph appears with f1(x) at the bottom.
(-) x ^ 2 (enter)
The (blue) arc appears on the photo
To undo the arc: "ctrl" "esc"
A different arc:
"menu" "3:graph/entry edit" "1:function"
(-) x ^ 2 (right space) divided by 3
"3:graph/entry edit" "1: function"
f2(x) appears at the bottom
Input (-) x ^ 2 / 5 + 3.5
Another colored parabola appears on the drawing!
To save the math image:
5: save as (choose a name)
"drag and drop bridge outline"
move cursor to "Save" "enter"
25) Recognizing the interaction of computer and handheld
TASK: Send outlined bridge to computer workspace display
Using the software on the computer, go to the "documents toolbox"
Look in the TI-Nspire CX CAS list of items
double click the .tns file you wish to open (drag and drop bridge outsline.tns)
The handheld edits will appear on your computer.
Cool feature: you can edit the graph from the handheld OR from your computer using the TI software platform.
