Icon legend: File with screen shots File with animated screen shots File with reviews Featured programs.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 R2 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).AutoFoil One of my pet peeves about my nSpire CAS, is that: although it is marketed as a CAS, it sometimes doesnt 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)(4x2)-like (in format) strings come up and become very tedious to solve or simplify. Thats why I figured out AutoFoil It saves time with the whole FOIL thing and saves paper space (And it helps me be lazy. 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. 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. Serial Para Ti Nspire Cas Vs Non Zip 3K 09Thanks 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 Be sure to plop a donation at the developers site to help fun continued FREE nSpire apps b2b.zip 3k 09-04-07 Base to base converter ver 1.1 This version works on both the Nspire CAS as well as on the non CAS variant. It can handle., E and bignums. Bernoulli Differential Equation v2.0 The program solves the Bernoulli differential equation being given as yg(x)yh(x)yn in the general form (constant Ci undetermined) or finds, as of v2.0, the numerical solution to Ci for an initial condition y(x0)y0. Documentation included on page 1.1. Boolean Syntax These functions provide a Boolean syntax wrapper for standard Boolean operators. It also generates truth tables and provides proof functions. Serial Para Ti Nspire Cas Vs Non Simulator Simulates DropsBuffons needle simulator Simulates drops of a needle on a sheet of paper with equally spaced lines. The probability of the needle crossing a line is a function of the needles length and Pi. Run the simulation to determine a numerical approximation to the value of Pi. Includes English and Portuguese versions. Calcalc 1.4.1 Calcalc 1.4 with bugfixes. Circle, Pole, Polar v2.00 Given a circle and an outer pole P0, a secant ( chord ) p with intersection points P1, P2 or the midpoint of a chord the program finds the unknown variables and the tangents T1, T2 which include P0,P1 and P2. Besides, the lengths of p, T1, T2, the angle alpha between T1 and T2 and the area A of the triangle (P0,P1,P2) are computed as well. A graph of the last calculation is provided on page 1.4. Clothoid Type clothoid(1) to draw a clothoid (also called Euler spiral or Cornu spiral) or clothoid(2) to draw a related curve. Complex Analysis Functions A library of functions for the TI-Nspire CAS for use in complex analysis. Includes functions for finding poles, calculating residues (including the residue at infinity), computing contour integrals, and (last but not least) Laplace and Inverse Laplace transforms. Completing the Square Quadratic Solver Takes a unformatted quadratic equation as a string, autodetects the variable, shows all work and solves the quadratic equation by using the completing the square method. It finds on the basis of pre-set conditions the functions of return R(x) and costs C(x) and calculates characteristic properties concerning both of them and their difference P(x) (profit). Curl, Divergence, Gradient v2.2 The program finds the curl and the divergence of a vector field andor the gradient of a scalar field. The coordinates may be Cartesian u,f(x,y,z), spherical u,f(r,theta,phi) or cylindrical u,f(r,phi,z) and are selected automatically by the program depending on the input variables. Both general and numerical solutions for a given point P(x0,y0,z0) as well as combinations like div grad u ( Laplacian operator ) are provided. Curvature of a Function The program calculates for four types of functions the curvature k, radius of curvature rho and the center of curvature (xc,yc). A general solution as well as a numerical result for any point xp of the function is provided.
