第m个文件扩展名是被称为派生数学文件,其中包括通过加载派生价值和功能。导出是一个计算机代数系统。它提供了精确的运算,因式分解,部分分式展开,方程求解,二维和三维彩色图,导数,积分,微分方程,泰勒和傅里叶级数,拉普拉斯变换,向量和矩阵。它会显示一个空白的界面中插入数字,表达式,符号和创建计算所需的一切。在MTH格式的文件可以打开与德州仪器导出在Microsoft Windows平台。 DFW是使用派生另一个文件扩展名。这是仅适用于Windows和DOS平台上推出,并同时使用,因为它很少的内存对于TI的袖珍计算器。由软仓库在夏威夷檀香山,后来由得克萨斯Intsruments拥有基于muMATH它被开发。它已于2007年终止离开派生6.1作为它的最后一个版本。 TI NSPIRE替换派生数学软件。
As of this writing, further development has been discontinued for Texas Instruments Derive, which is an educational application that was last sold in June 2007 by its developer, Texas Instruments, though support will continue to be provided by Texas Instruments to users of Derive. Similar features, compatibility support and functionalities that are available in the last version of Derive can be found in some of the recent applications from Texas Instruments. Most of these features and compatibility functionalities can be found in Texas Instruments Nspire among other latest releases from this developer, though improvements and upgrades of these functionalities have been incorporated into these applications.
