Question about Texas Instruments TI-89 Calculator

Ad

Hello,

It is my pleasure to give you the link to the manual for the TI89/TI92

http://education.ti.com/educationportal/downloadcenter/SoftwareDetail.do?website=US&tabId=2&appId=6129

I do not know what kind of work you do, but you should visit the site and Click the Download-->>Software menu. There are a lot of third party programs at www.ticalc.org (or com)

Hope it helps.

Hi,

a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US.

click here to Talk to a Technician (only for users in the US for now) and get all the help you need.

Goodluck!

Just open the Y= equation editor and enter your equation. Use X for T. Make sure the angle unit is in radians.

You can find the program editing menu under "Apps". Choose "New..." After you enter the name of your program, you will be able to edit it. To run it, go to the home screen (the screen where you enter mathematical equations), hit 'catalog', then 'f4', and choose the program from the list.

As for the coding itself, this site has a solid reference of many concepts and commands that are involved when programming for the TI-89: http://tibasicdev.wikidot.com/68k:home The best way to learn, however, is to play around and figure things out yourself. Programming for the TI-89 is much more powerful than it is for the previous TI calculators. Best of luck!

There are a few routines to solve simultaneous LINEAR equations that are embedded in the Operating system of the calculator.

If you need download and install instructions, you will find them here.

This book is what I used to help learn how to solve mesh circuits. A high education level helps. You just set it up as you see it in a simultaneous equation.

kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.

The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

TI-82: $89

TI-83 Plus: $79-99

Free TI-85: $0

TI-84 plus: $119.99

TI-84+SE: $129-139

TI-89 Titanium: $149

x^2+5x+7 won't factor any more.. if you're trying to solve it, do:

solve(x^2+5x+7=0,x)

solve(x^2+5x+7=0,x)

Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})

Put all of your equations right after the opening parenthesis separated by the word*and*, then a comma, then within curly braces each variable you want to solve for each separated by a comma.

Put all of your equations right after the opening parenthesis separated by the word

Just plug in one side of the equation and find the answer. Then plug in the other side and compare answers.
