However, as an interpreted language, it is generally not fast enough for a game, so for anything requiring fast processing, assembly language is required. This is, however, outside the scope of this Wikibook. Even though the language is slow, for most purposes it will serve admirably. Disp can accept an unlimited number of arguments separated by commas although it recommended to keep the number of arguments under 7 because after seven, for each consecutive argument the screen pushes everything else up passed the top of the screen, even the seventh pushes the first line up a slight amount , and will display each argument following the previous line.

Pause , Control F2 :Transfers 8 :1 , displays an argument, then pauses execution afterwards. The item to be displayed is outputted to the specified coordinates supplied to the function. It is useful for formatted display. Return , Control F2 :Transfers 8 :2 , displays an argument on the home screen, or just returns to the home screen if no argument is supplied.

For the sake that this can only be used in a function, the appropriate tags and a name are supplied for this example. This is the sixth in my Screensaver series for the z80 calculators, now ported to the TI A set of crosshairs moves randomly over the graphscreen until any key is pressed, when it quits instantly to the homescreen.

Alien creatures have broken into the Jupiter headquarters and sabotaged all systems and hid bombs in different corners and angles, which can destroy the headquarters and the two adjoining buildings any moment. It all depends on you. As secret agent Jupiter Jumpman you have the speed and experience to cross the aliens' plans and thus defend the headquarters. In this comprehensive platform game, the bombs have to be collected in 30 levels. At the same time some creatures as bats, birds or aliens, but also robots and missiles disturb you.

Also, collecting the bombs is a bit tricky. Either traps are triggered, i. The name of the level kind of contains directly what will happen! Seen as that, everything that moves should be avoided. This is 68k port of KermM's polygon drawer that is included in his excellent programming book. I only ported the source to 68k Basic. I wrote this to hopefully minimize code reuse for processing arguments passed to C programs, throwing exceptions for required arguments, filling in default values for optional arguments, and so on.

Hopefully, it will be of use to others as well. A grayscale breakout-like game with scrolling and 7 types of power-ups, including lasers and multi-ball. It has very smooth gameplay synchronized at 29 frames per second. Manage preferences Agree and Proceed.

There are also a variety of options that I added to provide the most convenience for you. Also, the user has more manually-controled options and less programed limitations.

The Newton-Raphson Iterative Method v1. Newton's Method Instructions: Run the program by typing nm in the home screen. Follow directions on screen - it's that simple. The reason I wrote this program was because most of the others ask for a range of accuracy. In this program, there is no range. The root will be at zero for as many decimal places as the calculator can compute.

The only possible let-down I can think of is that I left out the given number of itterations function. The itterations are, however, numbered if you only need a small number. It comes with all the possible options I could think of. Really nice! Newton's Method This is a simple program for newon s method. It s sometimes on the AP calc ab test. Anyways, you input the equation and a guess on the home screen and it displays 18 iterations on the I O screen.

The n-dimensional version of the fmin on TI User guide is included in the. Number of dimensions of function only limited by calculator memory. Numerica v1. It can find zeroes in a function using the bisection, newton-raphson, or regula falsi methods.

Interpolates with the secant, tangent, lagrange or taylor methods. Integrates with trapezoidal, simpson or MonteCarlo methods. And solves Diff. Numerical Integration Does various tasks of numerical integration, including calculating the errors involved in doing the Midpoint, Trapezoidal, and Simpson's rules. ODE Solver This program reconstructs the path of a particle using some initial data by numerically solving systems of second order ODEs.

Check readme for specifics. Indefinite Integrator This tiny bytes program will return the solution to an indefinite integration problem along with the constant.

The interface is very easy-to-use, and this program is as compact and optimized as it can get so it won't take up very much room on your calculator's memory at all. The result is nicely displayed. Rational Function Analyzer and Grapher This program analyzes functions which can be expressed as a ratio of two functions.

The functions can be any of a wide range of types, including polynomials, radicals, and absolute values, sometimes leading to two horizontal or slant assymptotes. The program determines any x- and y- intercepts, horizontal or slant assymptotes, vertical assymptotes, and, optionally, relative minima and maxima. The function is then graphed, showing all intercepts and assymptotes. It determines x- and y- intercepts, horizontal or slant assymptotes, vertical assymptotes, and, optionally, relative minima and maxima.

All results are copied to the home screen. The graph can be zoomed to examine different regions. Reimman Sums Reimman Sums is a program that calculates Reimman sums by using left hand, right hand, and mid-point rectangles as well as trapezoids. It lets you specify bounds and number of iterations, then saves them if you choose. Residue complex analysis In complex analysis, the residue is a complex number which describes the behavior of line integrals of a meromorphic function around a singularity.

Residues can be computed quite easily and, once known, allow the determination of more complicated path integrals via the residue theorem. Revoultion of Solids This is a program that has taken a long time to perfect. It finds the volume of a region between two curves revolved about any horizontal or vertical axis. Should be finally perfect. Super Riemann Sums v2. It can find the left Riemann sum, the midpoint Riemann sum, the right Riemann sum, the Riemann sum with the Trapezoidal rule, and the Riemann sum with Simpson's rule.

It is made easy to use but is also very efficient. You can display all at once in a graphical manner or find an individual one as a function. Riemann Sum Calculator Function to compute the Riemann sum of a function over a given interval. Gives exact results, by default. Syntax: riemann function,lower,upper,intervals. It has a dialogue box to make inputs easy and simple.

Riemann Sums Riemann Sums allows you to input a function in terms of x, an interval, and the number of rectangles. The first four choices allow you to perform individual calculations. Choosing All performs all of the first four options. Choosing About gives information about the program.

Choosing Quit ends the program. If you choose any of the options except Quit, after execution a popup will appear asking to run the program again or quit. Riemann Zeta This computes the well-known Zeta of x. Contains ideas from Riemann himself! Riemann Sums Calculator Calculates the right, left, and midpoint Riemann sums, plus trapezoidal and Simpson's approximations for integrals. Approximations v1 These programs provide an approximate numeric solution to an unsolvable first order differential equation given the initial condition at points along the given subinterval through Euler's Method and the Runge-Kutta Method.

Based off rules for TI plus. Simultaneous Differential Equation Solver v2. Simpson's Rule v1. It estimates areas under curves using this method. It's nice to use it to check your answers, if you are in calculus.

Slope Field Slope Field is a somewhat useful program for students who are in calculus. I only used it about twice for homework, but it was fun to make and it even creates some really pretty designs with the right equations and window settings. Sebastian's Calculus Package A package of more than 80 math functions and programs related to Calculus.

A must-have for all students who want to save time and make less mistakes. Includes sign charts, domain and range of functions, moving particle problems, differentiation and integration tools, and much more. Most parts are not related to others, so you can make any selection of sub-packages.

The index files contain helpful instructions and examples which you can read before installation on your TI If you have Windows 95 or later, be sure to download the setup program for this package.
