TI-85 Stuff
The TI-85 is one of Texas Instruments' popular graphing calculators. Information and software for the TI-85 and other Texas Instruments calculators can be found at Texas Instruments' web site and at www.ticalc.org.
The following are programs I and/or Andy Schechter have written for the TI-85. Click on any title to download the program. No shell is required; however, you will need a cable and the appropriate software to transfer them to your TI-85 from your PC.
These programs should run on a TI-86 as well, but I can't guarantee it.
The links labeled "ASCII" lead to ASCII files of the type that TI's link software exports. If you're considering typing a program in by hand, the ASCII file is what you want.
| Name | Description | Screen Shot |
|---|---|---|
| Integral Approximation (ASCII) | This 1285-byte TI-85 program uses several methods to numerically approximate definite integrals. The functon f(x) and the limits of integration, as well as the number of subdivisions are input by the user. |  |
| Conics (ASCII) | This 261-byte TI-85 program will graph any conic - parabola, circle, ellipse, hyberbola or line - that you enter in general form (Ax2 + By2 + Cxy + Dx + Ey + F = 0) as two functions (or one if B=0) using the current range and format. |  |
| Vectors (ASCII) | This 725-byte TI-85 program has four functions - add, convert between rectangular and polar, cross product and dot product - for dealing with 2-D vectors, in physics for example. |  |
| Euler (ASCII) | This 396-byte TI-85 program uses Euler's method to numerically approximate functions whose derivatives are defined in terms of x and y. |  |
| Exponential Growth (ASCII) | This 3160-byte TI-85 program calculates amounts, times and rates of change for exponential growth and decay. |  |
| Binex (ASCII) | Performs binomial expansion and probability. | No screen shot available |
| Chem (ASCII) | All purpose chemistry notes, designed for high school AP chemistry. | |
| Casino | Four games: blackjack, poker, slots and roulette. | |
| Factors (ASCII) | Lists integral factors of any positive integer. | |
| Lines (ASCII) | Midpoint, slope and distance between two points. | |
| Linear Motion (ASCII) | Position, distance, displacement, average velocity, maximum velocity and acceleration from x(t). | |
| Motion | Position, range, etc. given initial velocity & height. | |
| Physx (ASCII) | All purpose physics notes, designed for high school honors physics. | |
| Polymult (ASCII) | Multiply any two polynomials in x. | |
| PolyDiv (ASCII)* | Divide any two polynomials in x. | |
| Volume (ASCII) | Areas, volumes of rotations and perpendicular cross sections via integrals. |
