TAMUDFEQ 1.2

TAMUDFEQ 1.2 is a differential equations package written by Art Belmonte for the Texas Instruments TI-Nspire CAS Handheld and TI-Nspire CAS Computer Software. It is recommended to be used with TI-Nspire CAS Operating System 1.7. (The package will not work with the non-CAS handhelds or software since they lack symbolic capabilities.)

Install the package

Download the Package (above) to your Windows PC or Mac desktop. It contains the requisite TI-Nspire CAS libraries. Unzip the file to extract the folder TAMUDFEQ12_TNS.
Now transfer the .tns files contained in TAMUDFEQ12_TNS to the TI-Nspire MyLib libraries folder.
- Use the TI-Nspire Computer Link to install these .tns files on your TI-Nspire CAS Handheld.
- If you have the TI-Nspire CAS Computer Software on your Windows PC or Mac, just use the computer operating system to move the files.
Refresh your libraries.
- If you have a TI-Nspire CAS Handheld, do the following in the Calculator Application.
  - Press the MENU key.
  - Choose 1: Actions.
  - Choose 7: Library.
  - Choose 1: Refresh Libraries.
- If you have the TI-Nspire CAS Computer Software, just click on the Refresh Libraries icon in its toolbar. (Look at the tool-tips.)

Accessing TAMUDFEQ commands

When starting a new problem, run the activate command under atm_tamudfeq12 in the libraries portion of the catalog. (It is not necessary to reactivate the package on subsequent pages of a given problem; only if you start a new problem.)
Better yet, download Pre-activated templates. Unzip a folder and transfer it to TI-Nspire Documents folder on your handheld or computer. It consists of files which contain 5, 10, or 15 pre-activated problems. In practice, load a pre-activated template and rename it to (for example) Quiz7.tns or Exam3.tns, perhaps in a Differential Equations folder. This saves you LOTS of time since entry aids are automatically set up for each problem! There are three types of templates which contain different types of entry aids.
1. library shortcuts
2. inline commands
3. both
The activate command sets up groups of library shortcuts that make it easy to rapidly access the package commands. Read the Command Reference for complete details. There are three groups.
- e. eigenvectors (regular and generalized)
- l. linear ODEs (That's a lowercase letter L, not the numeral one!)
- s. Laplace transform methods
