 News Recommended Books TI-89 For Dummies Sat II Math With Ti 89 Cheating Random Findings Humor Etc

The TI-89 and the TI-89 Titanium are graphing calculators developed by Texas Instruments. They are differentiated from other graphing calculators by their powerful computer algebra system, which allows symbolic manipulation of algebraic expressions. For example, equations can be solved in terms of variables; most other calculators can only give a numeric result.

In the United States, the TI-89 is allowed by the College Board on all calculator-permitted tests, including the SAT, some SAT Subject Tests and the AP Calculus, Chemistry, Physics, and Statistics exams.

However, the calculator is banned from use on the ACT, the PLAN, and in some classrooms.

In many testing situations, the TI-89 and TI-89 Titanium, along with the HP-49 series, are the most powerful and function-rich graphing calculators that are permitted: the TI-92 series, with otherwise comparable features, have QWERTY keyboards that cause them to be considered small computers.

The main advantage of TI-89 is that, you can solve equations and unequalitites, whether they are algebraic, trigonometric, exponential, logarithmic, polynomial or one that involves absolute values. This is king of cheating as you do not need to know the related topic in debth and having to perform tedious and error-prone steps but it is permitted by College Board. You just need to learn a feq easy techniques.

But there are still more to what you can do with the TI; find period, frequency, amplitude, offset, axis of wave of a periodic function, find the maxima minima and zeros as well as the domains and ranges of all types of functions; perform any operations on complex numbers, carry out any computation involving sequences and series, perform matrix algebra, solve a system of equations for any number of unknowns and even write small programs to ease your life. Approximately half of math questions in the SAT Math section are based on the topics in which TI can help.

Unlocking the Power of the TI-89, September 30, 2005

By Naut Gauss (Tulsa, OK) - See all my reviews

"TI-89 ...For Dummies" has unlocked for me many useful features of this powerful calculator. The TI-89 is required for a sequence of classes I am taking.

The TI supplied manual reads like some poor engineer was asked to spruce up the notes from designing the thing. But CC. Edwards presents essential features in a clear, fun, and readable manner. I wanted skills that would help me quickly perform needed operartions and understand how to get out of quirky modes that you can blunder into.

Thanks, C.C., you did it! She is a good writer.

Good and bad, November 11, 2006

By Fred K. Johnson (Aurora, CO USA) - See all my reviews

This book is very good at what it does cover and very bad at what it doesn't cover. It's clear it was written by a mathematician. The topics and tricks dealing with functions and graphing are great. Anyone taking a math class such as Algebra, Trig or Calculus will be helped. It doesn't cover certain important topics at all or very lightly. There is nothing on programming.

Two pages are dedicated to writing your own functions with nothing on how you can use a user defined function in a formula.

While the book carefully explains how to make sure if variables are defined or not there is nothing on folders which would be a great help as the scope of a variable is a folder.

By organizing folders you can keep things seperated and track when variables are defined.

There is nothing on units of measure which is a strong point of this machine. That would be important in say a physics or EE class.

It has very little on statistics for someone in a statistics class.

The book that should come with the calculator, March 14, 2006

 By Robert L. Wilson "lifelong student" (Seattle, Washington United States) - See all my reviews
When you purchase a TI-89, you should be either directed to purchase the Dummies book for it, or it should be included with the device. More informative (and easier reading than the dry manual included) the Dummies book is excellent to assist you in the learning curve and get your money's worth out of the device.
My opinion is that the only dummies are those who do not make use of their Dummies books. Well written by knowledgable professionals who have a sense of humor.
