| **polygraf.zip** | 4k | 03-10-19 | | **Polynomial Root Finder and Grapher** This update of Polygraf() changes the method of data input, making entry more user friendly and also making it easier to notice and correct errors. Roots are found much more quickly than in previous versions, especially for higher degree polynomials. Polygraf() finds all roots, real, complex, and repeated, of an nth degree polynomial equation, finds minima and maxima, and then graphs the polynomial function. The function can be displayed in fully factored form and allows you to toggle between Auto and Approx displays for the roots and factors. The program uses the cZeros() function repeatedly, and in many cases returns results in exact form rather than decimal form. Polygraf() is my alternative to the TI Polynomial Root Finder, which sometimes introduces small imaginary parts to real roots and vice versa, especially for repeated roots. For a more comprehensive program which includes Polygraf() as well as easy to use programs (none of the usual ()'s, {}'s, or x's to enter) for multiplying, dividing, and factoring polynomials, and for analyzing and graphing rational functions, see Polynom(). |

This program multiplies polynomial functions. It uses the TI-89 expand() function, but input is easier, coefficients only, none of the usual ()'s, {}'s, or x's to enter. For a more comprehensive program which includes Polymult() as well as easy to use programs (none of the usual ()'s, {}'s, and x's to enter) for solving polynomial equations, factoring polynomial functions, graphing polynomial functions, multiplying and dividing polynomials, and for analyzing and graphing rational functions, see Polynom(). |

It includes Polygraf(), Polyfact(), Polymult(), Polydiv(), and Rat_Poly(), all of which can be downloaded and run separately, if desired. I run Polynom() from a keyboard program. The included programs solve polynomial equations, graph polynomial functions, factor polynomial functions, multiply and divide polynomials, and analyze and graph rational functions. The programs are easy to use; input consists of coefficients only, none of the usual ()'s, {}'s, or x's to enter. |

The program uses the cZeros() function repeatedly, and in many cases returns results in exact form rather than decimal form. Polyroot() is my alternative to the TI Polynomial Root Finder, which sometimes introduces small imaginary parts to real roots and vice versa, especially for repeated roots. In general, it is slower than the TI program, but the form of the results is usually more convenient. If you want to graph the function also, see Polygraf(). |

I spent a long time on ticalc.org trying to find a good distance formula program for the TI89. I did not find any as versatile as this one that I wrote.

New in version 1.1 is a midpoint finder! |
