This update changes the method of data input, making entry more user friendly and also making it easier to notice and correct errors.

polyfact.zip2k03-10-19File is not ratedFactor Polynomials
This is an update of Polyfact() which factors polynomial functions. The method of data input has been changed in this version, making entry more user friendly and also making it easier to notice and correct errors. Choose rational factors only, include irrational factors, or include complex factors to factor completely. Or do them in sequence to see the progression. Toggle the displayed factors between Auto and Approx mode. The program uses factor() and cfactor(), but the input is easier, coefficients only, no x's, ()'s, or {}'s. The factored forms are copied to the home screen so they can be more easily used in further calculations. For a more comprehensive program which includes Polyfact() as well as easy to use programs for solving polynomial equations, graphing polynomial functions, multiplying and dividing polynomials, and for analyzing and graphing rational functions, see Polynom().

polygraf.zip4k03-10-19File is not ratedPolynomial 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 update of Polynom() changes the method of data input in all of the included programs, making entry more user friendly and also making it easier to notice and correct errors. It includes the newer, faster version of Polygraf(), for solving and graphing polynomials. Polynom() is intended as a convenient way of running several programs concerning polynomial functions. 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.

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().
