The TI-92 is my main calculator. If you are unframilliar with this calculator it has a 68000 Motorola processor that was used in early Macintosh computers. The current selling vertions of this calculator have 128K of memory. The calculator has the ability to graph in rectangular, polar, parabolic, sequence, and 3D modes. The calculator has a Interactive Geometry application that lets you draw geometric figures including circles, lines, segments, polygons, and others. The calculators text editor allows you to type documents out on the QWERTY kebord it has and upload it to a computer to be printed. The html for this site was, in part, typed on my calculator! The calculator suports programing in a form of BASIC language. Also utilities have been made that let programs be writen on computers and put on the calculator in Assembly language. The TI-92 allows for symbolic manipulation of equations and will display them as seen in textbooks. This also allows for solving, factoring, intigration, differentiation, and many others with equation outputs. Also output can be set to exact values so you will get cos(225¡)=-sqr(2)/2 instead of cos(225)=-.7071067.

My small Program Archive Here are some screen shots from the TI-92:

A home screen with equiations, solving and "Pretty Print" on.

Split Screen on with a 3D graph and some 3D equations

A little bit of logic, Calculus, and Greek

There is now an upgrade to tht TI-92, The TI-92 Module includes new software and more memory.
