http://www.ticalc.org/archives/files/fileinfo/458/45850.html
This program is an expansion of APOLYFC9 in this directory, for those who wish to also be able to find the non real roots of a one variable polynomial. You enter the equation as it stands in the text book. You can use any variable A to theta. Then you answer wether to search for non real roots or not. Only rational roots though, not irrational. The linear factors are found in the conventional way, and above that the program attempts to "look" at the rest. Several bug fixes in this version.Tue, 16 Oct 2018 18:47:48 GMTTI-83 Plus/TI-84 PlusAPOLYFC0
http://www.ticalc.org/archives/files/fileinfo/458/45851.html
This program is the same as APOLYFC8 in this directory, except that it can also find the non real roots of a one variable polynomial. The linear factors are found in the conventional way, and above that the program attempts to "look" at the rest. First you enter the degree, then the coefficients, and then you answer wether to look for non real roots or not. Only rational roots though, not irrational. Bug fixes in this version.Tue, 16 Oct 2018 18:47:43 GMTTI-84 Plus CSE/CE BASICAPOLYFAC10

http://www.ticalc.org/archives/files/fileinfo/471/47168.html
This is a set of functions for the TI-Nspire CX CAS to complement a textbook on Markov Chains. The functions wrap the Markov chains and state vectors with header labels and automat some of the more arduous calculations. The functions include: - Templates for creating augmented Markov chains and state matrices with header rows and columns. - Functions to work with the augmented Markov chains to compute powers and state transitions. - Functions to determine whether Markov chains are regular or absorbing. - A function to compute the equilibrium vector for a regular Markov chain. - A function to normalize an absorbing Markov chain. i.e., Float absorbing states to top/right. - A function to compute the fundamental matrix for an absorbing Markov chain. - A function to compute the long term trend for an absorbing Markov chain. The package includes documention and source code and is free to use and distribute.Tue, 16 Oct 2018 16:57:27 GMTTI-83 Plus/TI-84 PlusRectangular Prism Tool
http://www.ticalc.org/archives/files/fileinfo/471/47167.html
This is a program I made to help me find the surface area, and the volume of any rectangular prism. It deletes the variables as soon as it displays the product. It isn't optimized to save space, but is only 348 bytes. It also reminds you that the answer is cubed, or squared.Wed, 10 Oct 2018 17:52:46 GMTTI-83 Plus/TI-84 PlusVat Sort
http://www.ticalc.org/archives/files/fileinfo/471/47115.html

http://www.ticalc.org/archives/files/fileinfo/450/45048.html
This program gives you the integral factors of most polynomials in one variable, and writes them out in factored form, when you enter them like they would appear in a text book. For example, 64x^6-729, is factored into: (2x-3)(2x+3)(4x^2+6x+9)(4x^2-6x+9). 8x^3+27, is factored into: (2x+3)(4x^2-6x+9), x^4+2x^2-15, is factored into: (x^2-3)(x^2+5). You can use any variable from A, to Theta, and there can be like terms in the expression, and it doesn't matter in which order they are entered. UPDATE: The program is basically the same as AFACTOR6, but with proper input and output. It has a subroutine, APOLYSUB, that needs to be installed.Tue, 25 Sep 2018 16:47:30 GMTTI-83 Plus/TI-84 PlusAPOLYFAC

This program gives you all the integral factors of most polynomials you'll ever encounter in school.

It is also very fast compared with other programs of this type. You enter the degree and then the coefficients of the polynomial.

http://www.ticalc.org/archives/files/fileinfo/471/47126.html
This program can factor all real integer polynomials that have real integer factors. i.e. when the function-curve crosses the x-axis. It has tricks like taking the second and third roots out of the possible divisors conditionally. It uses the polynomial division algorithm for both factors like, {7,0,0,0,0,5}, and {2,1,1}, to confirm they are correct. Unlike AFACTOR4&5, it takes on only integer polynomials. You enter the coefficients as a list, and you get the factors as lists. UPDATE: The program is now much faster in some cases, and can handle a polynomial like {4,0,0,0,0,0,0,0,-9}.Tue, 25 Sep 2018 16:47:05 GMTTI-84 Plus CSE/CE BASICAPOLYFC1

The program finds for the differential equation ( d. e.) of a forced vibration given as m*d2y/dt2 + d*dy/dt + c*y = F0*cos(omega*t) or m*d2y/dt2 + d*dy/dt + c*y = F0*sin(omega*t) or a combination of both the exact solution dependant on preset initial conditions t0, y0(t0), y'0(t0). V1.11: sign error in the combination case fixed.Fri, 21 Sep 2018 16:13:25 GMTTI-83 Plus/TI-84 PlusFACTOR
http://www.ticalc.org/archives/files/fileinfo/423/42305.html
FACTOR: This program finds the linear factors of a polynomial of one variable. Try for example 117X^4 -20X^3 -390X^2 +20X +273. If the polynomial only has rational factors it will be completely factored. The above example will factor as (X-1)(X+1)(9X+13)(13X-21), If the polynomial has irrational or imaginary/complex roots in addition to rational roots, or if the program can't find any factor, the program will show the coefficients of the remaining polynomial. For example: X^3 +X^2 +X -3, will give a linear factor of (X-1), the program will then display: OTHER FACTOR: {1 2 3}. Which means that 1X^2 +2X +3, is another integral factor. If the program can't find any linear factor, or when there is not enough of them, it tries a substitution for X^2. It can then find factors like, (AX^2+B). This makes it more likely that it finds all the integral factors. Try for example: X^5-X^4+2X^3-2X^2-15X+15.The program is now three times faster for the first equation above, than the original version. FACTORS: This is the same program as FACTOR, except that if the equation will not allow itself to be factored at all, or partly, it ,or the rest of it, will be printed out on the graph screen. This comes at a cost of an additional 128 bytes.Mon, 17 Sep 2018 16:31:16 GMTTI-84 Plus CSE/CE BASICFACTOR

http://www.ticalc.org/archives/files/fileinfo/471/47155.html
Made for the game "Keep Talking and Nobody Explodes". My goal was to create a program that could solve a module faster than what could be done practically between a defuser and an expert. Most of these modules are not interactive, so the calculator does all the 'heavy lifting' for the defuser. Some modules, such as "Keypad" and "Emoji Math" are so visual, that I think it would be impractical to try and communicate the pictures to a machine that works in text and equations. However, the calculator does excel at modules like "The Gamepad" or "Skewed Slots," which have longer manuals to read and are tedious to solve as an expert.Sun, 16 Sep 2018 17:52:40 GMTTI-84 Plus CSE/CE BASICTIbelius Sheet Music and MIDI Sequence Editor
