Title Rational (Polynomial) Function Analyzer and Grapher
Description This update of Rat_poly() changes the method of data input, making entry more user friendly and also making it easier to notice and correct errors. Rat_poly() analyzes functions which can be expressed as a ratio of two polynomial functions. It determines x- and y- intercepts, horizontal or slant assymptotes, vertical assymptotes, and, optionally, relative minima and maxima. All results are copied to the home screen. The function is then graphed, showing all intercepts and assymptotes. The graph can be zoomed to examine different regions. For a more comprehensive program which includes Rat_poly() 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().
