 Name Size Date Rating Description (Parent Dir) folder Up to TI-89 BASIC Math Programs fibonaciexp2.zip 2k 14-06-30 Fibonacci Sequence (optimized for large terms)Find the nth term in the Fibonacci Sequence, but is significantly faster for finding the 56th term and beyond (i.e. terms in the hundreds of billions). Negative numbers are not supported. 44 bytes. Input must be an *exact* integer, not an *approximate* integer. fs.zip 416k 14-02-07 Fourier seriesThis program calculates Fourier series coefficients (a0, a(n), and b(n)) of a given function. The function can have any number of piecewise continuous intervals. Results will be stored in one letter variables “o” (=a_0), “a” (=a_n), “b” (=b_n) and “f” (= sum of the series as a function of “k”). Resulted coefficients are a function of “n”, therefore, for example, finding a(15) would be easy (type a|n=15 in the entry line)... seri.trianglr.zip 1k 12-07-09 Triangular SeriesImplements an efficient algorithm for computing nth elements of the triangular number series. seri.spread.zip 1k 12-07-09 Spread SeriesReturns elements of the spread series, which is essentially a Chebyshev series of the first kind. seri.chebyshv.zip 1k 12-07-09 Chebyshev SeriesReturns elements of the Chebyshev series. fsgen.zip 3k 11-10-26 Fourier Series GeneratorReturns a specified number of terms of the Fourier series expansion of the given function over a period. Good for checking the accuracy of results or just having fun. pascal_row.zip 2k 11-06-23 Pascal's Triangle RowThis program returns the given row of Pascal's triangle as a list. This program sacrifices speed for a small size, so beware. Tip: it can also be used to find the coefficients of a binomial expansion. tribonaci.zip 1k 11-06-15 Tribonacci SequenceObtain the nth Tribonacci number without simply recursively calling itself upon smaller and smaller numbers. This program is much faster and can generate exact values for up to about the 60th term. seriesunk.zip 1k 11-06-15 Series SolverA valuable program that can solve many different aspects of both geometric and arithmetic series. Makes use of actual formulas, not simple for & while loops, so unknown variables are supported. Makes use of local functions so as to speed up program execution, as well. perinseq.zip 1k 11-06-13 Perrin SequenceObtains the nth term in the Perrin Sequence. fibonaciexp.zip 1k 11-06-02 Fibonacci SequenceFind the nth term in the Fibonacci Sequence without simply recursively calling itself upon smaller numbers. This allows it to work on negative term numbers, too. exponentialfourie.zip 148k 07-10-27 Exponential Series of Fourier - Step by step[English]:The program found the exponential series of fourier of the function that the user have entered, allowing to keep the partial results in home. They will be been able to work values symbolics and numerics, and the program will propose possible values of "n" that generate indetermination in Cn.If the user wished to find the series trigonometrical, the program showed An, Bn, Ao/2 and the result of the trigonometrical series.(English version included)[Spanish]:El programa hallara la serie exponencial de fourier de la funcion que el usuario haya ingresado, permitiendo guardar los resultados parciales en home. Se podran trabajar valores tanto simbolicos como numericos.El programa propondra posibles valores de "n" que generen indeterminacion en Cn, pero de todas formas el usuario podra modificar y supervisar estos valores de "n".Si el usuario deseara hallar la serie trigonometrica, el programa mostrara An, Bn, Ao/2 y el resultado de la serie trigonometrica (Version en Español incluida, con su manual).Works with ti-89/t,v200,ti-92/p. fibphi.zip 45k 07-01-07 Fibonacci Series Program version 1.0This is a great small and fast program that shows the relationship between phi and the Fibonacci sequence. See the screenshot. An interesting program to watch. A must download! fibonaci.zip 2k 06-04-19 Fibonacci Sequence GeneratorThis set, for the TI-73 -- V200, generates the Fibonaci sequence and stores it to a list. When running, it may appear to do nothing - it's actually working almost a fast as possible by not displaying results until the end. modfib.zip 4k 05-09-13 Modular Generalized Fibonacci Functions v1.0Collection of functions that will very quickly calculate the values of the Fibonacci, Lucas, Generalized Fibonacci, and Perrin Sequences to any modulus. Speed improved by using modular exponentiation with the Q-Matrix method, performing 32-digit calculations in about 15sec and 64-digit calculations in one minute. programmefourrier.zip 271k 05-04-19 Fourrier analyseA french program which permit to find an and bn coefficient of Fourrier's series. Ce programme trouve an,bn, valeur moyenne, valeur efficace, taux de distorsion, équations des harmoniques jusqu'au rang voulue, representation graphique du signal avec autant d'harmonique qu'on veut. La différence avec les autres est que la periode peut être composé d'autant de fonctions qu'on veut. lgib20.zip 15k 04-11-20 General Fibonacci Final Digits 2.5Function developed for the high-speed calculation of the final digits of any Generalized Fibonacci Number G(a,b,n). Configurable to calculate any number of final digits up to two hundred or more. Configuration is now nearly twice as fast. Returns twenty digits in less than 8sec on the V200 - 17sec absolute worst case. Available for the TI-89/ 92Plus/ V200. Added a version for the TI-92. Example: Last eighty digits of the trillionth Lucas Number are returned in 12.8sec and are ... 8107402237 8151629520 2428526180 8761835664 0376812699 1914147577 6463747024 5361328127 hfib.zip 22k 04-09-27 Big Fibonacci Calculator v1.7Calculates, in just a couple seconds, very large Fibonacci Numbers that would normally exceed the calculator's abilities. These functions are now extended to include the Lucas Numbers or any other Generalized Fibonacci sequence. The companion functions provide further information useful for the study of the digits of any Generalized Fibonacci sequence. Examples: The one-trillionth Fibonacci Number has 208987640250 digits and begins 425842268899. The last eight digits of the one-billionth Lucas Number are 61328127. Included are versions and source code for TI-92/92+/V200, and also the TI-89 Titanium. fib.zip 1k 04-08-24 Fibonacci NumberThis is a simple and very quick function that will return the nth term of the Fibonacci Sequence. Only 52 bytes! pascaltri.zip 1k 04-04-18 Pascal Row FinderThis function can find any row of Pascal triangle. For example, if you type in pascal(8) at the home screen, the program will return, "1,8,28,56,70,56,28,8,1", which is the numbers in the 8th row of the triangle. See animated screenshot for more info. pascal.zip 3k 03-08-06 Pascal's TriangleThis is a function that efficiently returns the row or selected portion of pascal's triangle as a matrix. All you do is enter pascal([row start],[row end]) and it will return those rows inclusively, or enter pascal([row],[row]) to receive only that row. pascal68k.zip 3k 03-06-03 Pascal's Triangle MatrixThis stores many rows of pascals triangle to a matrix for easy viewing. Just type in 'pascal(x)' where x is the number of rows. When finished type in pas to see the matrix. fibonacc.zip 1k 02-04-30 Fibonacci Sequence 1.1This program will give you the Fibonacci sequence.This new version is faster than the previous version. approxiamtions.zip 3k 01-06-11 Approximations v1.2Calculates the Linear/Quadratic Approximations and displays the first 6 polynomials for the Taylor/Maclaurin seriesV 1.2 adds the Delete Variables function.
