The TI-89 and the TI-89 Titanium are graphing calculators developed by Texas Instruments (TI). They are differentiated from most other TI graphing calculators by their computer algebra system , which allows symbolic manipulation of algebraic expressions—equations can be solved in terms of variables— whereas the TI-83 / 84 series can only ...

The statistical, graphical, and symbolic capabilities of the TI-89 make it a powerful tool for investigating and developing mathematical concepts. In this session, we will explore some of the main features of the TI-89 and work on some activities designed to help develop students’ understanding of various concepts and procedures

TI-89是德州儀器公司於1998年開發的一款圖形計算器。 該圖形計算器配有160×100像素解析度的 液晶屏 和 快閃記憶體。 TI-89 Titanium作為TI-89的後繼者於2004年夏天發布。

TI-89 于 1998 年开发。其配备了一个 160x100 点阵液晶屏幕、一个大容量闪存和德仪高级数学软件(即其内置的CAS系统）。 TI-89 同 TI-Nspire系列 为德仪热销机型。2004 年夏天，TI-89 被 TI-89 钛版替代。 TI-89 使用了 16 位的摩托罗拉 68000 处理器。

使用EE Pro功能之前最好是检查一下内置的函数是否正确，比如图中EE pro内置的NMOS 转移特性曲线 是错误的。 如果你是想考试用，那确实非常有用，比如 卡诺图化简 、傅里叶变换、Y-Δ变换、留数计算、 Bode图 等等，还带了一些常用公式。 不过如果你都会这些，同样的价格干嘛要买个老旧设计的计算器，直接买正版Matlab玩好了。 TI-89 Titaniumhttp://education.ti.com/download/en/US/B89A02AE62DC40D7870EE9B6370A1865/EC65C36B6AE5…

Use a TI-89 online with your Desktop, Tablet, or Mobile. Utilize web-based convenience by having access to a TI-89 online at any moment with the device of your choosing.

In this lesson you will reset the TI-89 to its factory default settings and adjust the calculator's contrast. Then you will learn how to go to the Home screen and you will learn about the four basic parts of the Home screen.

EVALUATE A FUNCTION - TI 89 or 92. Introduction The instructions for entering, running, exiting, and editing are the same for any program. The actual program on this sheet allows you to quickly evaluate a function. This may be helpful when determining a reasonable window for graphing or investigating the value of a limit.
