Texas Instruments TI-89 Tip List page 2

Some tips include code listings, which can be typed in. Most of the code is included in a zip file called
tlcode.zip. I use lots of comments and white space in these listings, so you will save considerable RAM
or archive memory by deleting these comments. Beginning with version 9.0, the code listings shown in
the tips are not the same as those in the tlcode.zip file. The code shown in the tips contains
explanatory comments. Those comments are not actually included in the tlcode.zip versions, to reduce
RAM/flash requirements. Code from earlier tip list versions may still have all the comments included.
The tips are organized in these sections:
[1] Miscellaneous: Tips that do not fit in any other category, as well as humor and hardware
[2] Computer Algebra System (CAS): Using the CAS for symbolic algebra
[3] Data structures: Working with matrices, lists and data variables
[4] Graphing and plotting: Function graphing, data plotting, operations on the graph screen
[5] Graph-Link Cable and Software: Using the TI GraphLink cables and software
[6] Math: Mostly numerical mathematics
[7] TI Basic programming: Programming techniques, tricks and work-arounds
[8] String variables: Manipulating string variables
[9] User interface: User input and output, dialog boxes and results formatting.
[10] Units Conversions: Using the built-in units conversions
[11] Solving: Using the various solving functions, including solve(), nsolve() and csolve()
[12] C Programming: A few tips on writing and using C and ASM programs
There are also a few appendices of reference material:
[A] Anti-tips - things that can't be done: Summary of calculator and CAS limitations
[B] More resources: Includes FAQs, TI documentation and useful web sites
[C] Glossary: of common and obscure terms
[D] Quick reference guide: to calculator commands and functions
[E] Tip list programs and functions: Alphabetic list of all routines in tlcode.zip
Note that the table of contents includes active links to all the tips.
I hope you find this useful or interesting, and that you will consider contributing your ideas and
corrections to this list.
