P.3 Rational Exponents and Radicals

Radical:
This program simplifies radicals. Enter a number and it will simplify the radical
that is the square root of that number. Here's the good part though - the number
doesn't have to be a positive integer! It can be positive, negative, whole, or fractional,
and this nifty program will simplify it! (However, if you enter a negative number,
you will get an error if you have your calculator set to real answers only. To set
your calculator to handle imaginary answers, go to your Mode and set it the second
to last option to something other than REAL.) Has a nice interface too. It uses variables
A, B, C, D, E, and F, but before it does anything, it stores their values into a
list variable it creates which is called LV, and when it is done it sets those variables
back to their former values, and it then deletes the list variable LV. If you have
any comments or find any problems with the program, email me at csrstka@earthlink.net.
Thanks!

Polyfctr:
It is slow, but sure! Answers are output as lists, in decreasing order of x.
For example, to factor 2X^3-3X^2-45X-54:
DEGREE?
?3
?X^3
?2
?X^2
?-3
?X
?-45
?
?-54
{2 -3 -45 -54}
{1 3}
{1 -6}
{2 3}
Therefore the factors are (X+3)(X-6)(2X+3).

Gauss-Jordan elimination demonstrator:
ACKNOWLEDGMENT
GAUSSIAN.83G is a group file containing the programs GAUSSIAN.83P, GAUSSNEW.83P,
and GAUSSCLN.83P. These programs were written by John Powers of the TI Graphing Team
and are released to the public domain. You may copy and change these programs.
INTRODUCTION
This program demonstrates the Gauss-Jordan elimination technique to solve a system
of equations. The action taken and the resulting matrix is displayed after each step.
The SWAP step lists the numbers of the rows swapped and the result of the matrix
after the rows are swapped.
The DIVIDE step displays which row is being divided through by the pivot.
Subsequent SUBTRACT steps indicate which row is being reduced by subtracting a multiple
of the pivot row.
HOW TO USE GAUSSIAN
This program reduces matrix [A] in place. Formulate a system of simultaneous linear
equations as an Nx(N+1) matrix in variable [A]. Run GAUSSIAN to watch step-by-step
Gauss-Jordan elimination.
The program pauses after each step to allow the user to scroll the resulting matrix.
Press [ENTER] to continue with the next step.
Program GAUSSNEW generates a new matrix in variable [A]. It prompts for the number
of matrix rows. Type
prgmGAUSSNEW
prgmGAUSSIAN
to generate a new random matrix, display it, then begin the elimination process.
Auxiliary routine GAUSSCLN cleans up matrix entries which are close to zero. |

vertical. In both cases c^2=a^2+b^2. An exception case in the output will flag a
degenerate hyperbola when a=b=c=0. In this case, the program will output the center,
vertices, foci and end points of the conjugate axis as coinciding at the same point.
The graph will be two lines intersecting lines through this common point.
