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. One of these things that fail is "FOIL"-ing, also known as First Outer Inner Last. 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. 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). (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.

WebPlot(function, start, iterations) displays cobweb and time plots for a population over many generations, using Calculator, L&S, G&G and D&S.TI-Nspire BASIC Math Programs. The comment line will appear in the Catalog if defined as LibPub.ĭefine variables you don't need to survive the program as "Local".įirstPrinciples(function) shows the step-by-step process and displays the function and derivative graphically. The "newton" program uses a function which has already been defined as f(x). Let's try something a little more challenging. Would give the list of numbers from 1 to 10. If LibPub is included in the definition and the file that contains the program or function is placed in the MyLib folder, then it can be accessed any time from the Catalog. What about solving equations: do we really need to specify the variable when I am just solving in x?Īnd wouldn't it be nice to integrate a function and get the constant term? I use the computer version of TI-Nspire much more than the handheld, which is great until I want access to one of those special characters that are on the keypad, but not on the keyboard! You should also check out John Hanna's TI-Nspire page and his Programming Intro. The actual QuadSolver.tns document is also available for download.įor a somewhat fuller, more complete introduction to TI-Nspire programming, read my online Intro to Programming TI-Nspire. Just getting started with TI-Nspire programming? Then you may like to work through a simple quadratic equation solver as a first program. They contain many useful programs, including those shown here. The documents add.tns and add2CAS.tns are collections of useful programs that I have collected together to place in the MyLib folder of my current (1.3) version of TI-Nspire. Programming on the TI-Nspire platform has come a long way in a very short time: from almost nothing at release in August 2007 to a dedicated environment with lots of potential by January 2008.
