My TI Programs

The following table gives the program name, the file names, the name of a file that holds a listing of the program, and a brief description of some TI graphing calculator programs that we have developed and/or used in the class. They are in alphabetic order. Names that end in .83p have been saved in TI-83 format: you can load these onto a TI-83, TI-83Plus, or TI-84Plus. Names that end in .8xp have been saved in TI-83Plus format: you can load these onto a TI-83Plus or a TI-84Plus. [They cannot be loaded directly onto a TI-83.] Names that end in .89p have been save in TI-89 format.

Note that the file names are links to the particular files. Right-click on the file name and download (save link as) the file to your computer. Then you may use TI-Connect to transfer the file to your calculator.
Program Name File Names Program Listing Brief Description of what the program does

APPROACH approach.83p
approach.8xp
approach.pdf Program to get values along a straight line approaching a goal point for a two variable function that the user enters in terms of f(a,b). Thus, to look at f(x,y)=x^2+y^2 -3x +8sin(y), enter the function as A²+B²-3A+8sin(B)

APPROAC2 approac2.83p
approac2.8xp
approac2.89p
approac2.pdf approac289.pdf Slightly improved program to get values along a straight line approaching a goal point for a two variable function that the user enters in terms of f(a,b). Thus, to look at f(x,y)=x^2+y^2 -3x +8sin(y), enter the function as A²+B²-3A+8sin(B). Both the 83-84 and the 89 versions use a menu to direct the program, but the 89 version operates in a slightly different fashion.

APPROAC3 approac3.83p
approac3.8xp
approac3.89p
approac3.pdf approac389.pdf Slightly altered program to get values along a straight line approaching a goal point for a two variable function that the user enters in terms of f(a,b), and, as successive points are generated, the program calculates the slope between the previous point and the new point. Thus, to look at f(x,y)=x^2+y^2 -3x +8sin(y), enter the function as A²+B²-3A+8sin(B). Both the 83-84 and the 89 versions use a menu to direct the program, but the 89 version operates in a slightly different fashion.

C13TTR c13ttr.83p
c13ttr.8xp
c13ttr.89p
c13ttr.pdf
c13ttr89p.pdf Program to solve the max volume of a rectangular box within a triangular, truncated room, as per the kind of problem found at the end of Chapter 13 in the LaGrange multiplier section.

COORD3 coord3.83p
coord3.8xp
coord3.pdf
Program to convert between rectangular, cylindrical, and spherical coordinates.

GETPLANE getplane.83p
getplane.8xp
getplane.pdf
Program generates the equation of a plane given the coordinates of three non-colinear points. Note that the GETPLANE program requires the calculator to have the program TOSTR installed.

SPHERE sphere.83p
sphere.8xp
sphere.89p
sphere.pdf sphere89.pdf
Program finds the general form of a sphere, or rather a hypersphere, in an n-dimensional space given the coordinates of n+1 points. For two-space, that is a circle from 3 points. In three-space, that is a sphere form 4 points.

SPHERE3 sphere3.83p
sphere3.8xp
sphere3.89p
sphere3.pdf sphere389.pdf
Program finds the general form of a sphere in an 3-dimensional space given the coordinates of the endpoints of a diameter.

THREESPC threespc.83p
threespc.8xp
threespc.89p
threespc.pdf
threespc89.pdf
Introductory program on doing vector calculations in three-space. For two vectors, the program will find the dot product, the cross product, the angle between them, the unit vectors in same direction, the directional angles, and the projection of one onto the other.

TOSTR tostr.83p
tostr.8xp
tostr.pdf
This is a subroutine that formats numbers as text. The TOSTR program should never be run as is. It is called by other programs.

VECT1 vect1.83p
vect1.8xp
vect1.pdf
Program developed in class to input the tail and head of a two dimenional vector and compute the components, the magnitude, and the unit vector in the same direction.

VECTORS3 vectors3.83p
vectors3.8xp
vectors3.89p
vectors3.pdf
vectors389.pdf
A more complete program to deal with 3 vectors in three-space. The program finds the dot products, the cross products, the magnitudes, the angles between vectors, unit vectors in the same direction, directional angles, and projections.
