advreg.zip33k14-10-12File is not ratedAdvanced Regression for TI-Nsprie CAS
(Update: corrects a problem created by the latest update.) This program fits data to an arbitrary function, i.e., to functions that are not necessarily linear in their parameters. The outputs from the program are 1) a statement as to whether the convergence critera was met, 2) the iteration matrix showing the progression of estimated parameters and associated sum-of-square errors, 3) the ANOVA matrix, 4) a vector of the standard error of the regression and R^2 stats, 5) a matrix of the estimated parameters with their standard errors, t values and probabilities, and 6) the fitted equation (as sometimes simplified by the software).
autofoil05.tns.zip3k11-06-02File is not ratedAutoFoil
One of my pet peeves about my nSpire CAS, is that: although it is marketed as a CAS, it sometimes doesn't work the way I expect from a $150 device. One of these things that fail is "FOIL"-ing, also known as First Outer Inner Last. When working with many math equations such as factoring or quadratic stuff, many (2x-4)(4x+2)-like (in format) strings come up and become very tedious to solve or simplify. That's why I figured out AutoFoil! It saves time with the whole FOIL thing and saves paper space! (And it helps me be lazy. Cheesy ) This program is also very easy to work with. In fact, with the recent 3.0 update, a wizard for AutoFoil has been implemented. But to keep nice with 2.0 users, I have also included a "legacy" version inside the program file. Smiley The program is very straight-forward. Give the required inputs and you're done. For the legacy version however, you must include in this format: (f1,f2,f3,f4). Commands: (Must be accessed from the library function, be sure to refresh libraries) *autofoil: Launches the autofoil wizard *autofoillegacy: (f1,f2,f3,f4) Takes the inputs and simplifies it using the FOIL method. *about: credits and such. Thanks for your interest in my app! The Haus of AnhHai develops quality applications for a variety of platforms, such as nSpire, 84SE, Java, Android, Windows and Mac!

eulprgm.zip5k13-12-24File is not ratedEuler's Method
Euler's Method allows you to input an expression for dy/dx, start of interval, end of interval, initial value, and a number of steps. If you are given step size (h) instead of number of steps, just enter 0, then enter the step size. The program will then print out a 3 row matrix containing the x, y, and delta y values rounded to three decimal places. It will also print out the answer in the form of a (x,y) coordinate. Finally it will store into a variable called "fulle" a matrix containing all the exact values without rounding. Example: Problem: Find the value of y when x=0.7 for dy/dx=y+x starting at (0,3) and using 5 steps. Program: 1. dy/dx= y+x 2. Start of interval= 0 3. End of interval= 0.7 4. Initial Value= 3 5.

formulum.zip98k10-12-10File is not ratedFormulum - Geometry/Math Program
Formulum is one of my most important achievements, an open-source program that calculates areas and volumes of geometric figures and solids given values like the radium or the height. So, the user gets a fast response of what the volume of a sphere is, simply by entering the radium. I try to optimize my scripts as much as I can so that programs run fastly and smoothly, just like every computer user wants. Since Formulum is open source, everyone can edit it and make new versions. However, official versions are released by me only. Save it in MyLib folder. Also, this is version 2.3, not 2.2 unlike the name of the folder. Again, save it in MyLib folder.

function.zip8k10-01-18File is not ratedComplete Function Analyzis
This is a world first! The program gives you all you need to know about a function ! In order to analyze a function, you have to enter its variable and its domain. For example, we'll take ln(x), defined on 0;+infinite. You will just have to enter : analyze(ln(x),x,{0,+oo}). (oo bzing the symbole of infinite, obtained by pressing Ctrl-i , complex i). Same for the funciton f(x)=x^2 on the specific domain [0,100], just type: analyze(x^2,x,{0,100}). The final given result is actually a matrix, due to a lack of programming capability on the NSpire. The matrix gives you the summary of what you need to know about the function. Zeros, Derivative, Limits, Variations... Note : The program should work with most common functions. If you notice any weird issue, please fell free to contact me and report the issue :) Also available in french
