POLYNOMIAL
‰          Programs like this can make it fun to play with
‰           math, so that˙you can get a feel for just what
‰          complicated mathematical˙functions model.

        †POLYNOMIAL‡  is an interactive graphing package  that
        may  be  used  to˙graph  any polynomial or algebraic
        expression  of  one variable˙using  real  exponents,
        trigonometric        functions        and        the
        standard˙mathematical   operations    of   addition,
        subtraction,   multiplication˙and    division.   Its
        primary purpose is to allow  the  user  to explore˙a
        specific  mathematical  landscape,  the character of
        the curves˙generated by polynomials and other single
        variable functions and˙change the parameters  of the
        function  to  determine  how such˙changes modify the
        graph that is produced.

        In  practical  terms, other than  for  second  order
        polynomials˙(‰parabolas‡),  it  has   previously  been
        virtually impossible to˙discover the nature  of such
        curves, even for those  who  ‰like ‡graphing.  This is
        primarily   due    to    the    great    number   of
        tedious˙calculations and great chance for  errors to
        occur when actually˙plotting the points with pen and
        paper. †POLYNOMIAL‡ eliminates˙that tedium, eliminates
        all of the errors  of  graphing  and allows˙infinite
        exploration of the patterns generated with ease.

        †POLYNOMIAL‡ allows the user to zoom in on any segment
        of the graph˙and then  to  redraw  that segment in a
        window located anywhere on˙the screen  and occupying
        any portion  of  the  screen.  This  process˙may  be
        repeated  indefinitely.  This may  easily  result in
        a˙magnification of ‰100,000,000‡ or more.

        While   †POLYNOMIAL‡  is  primarily  designed  as   an
        educational   tool,   it˙allows   a   grid   to   be
        superimposed on the graph, scaled to the size˙of the
        current  graphing window and thus enabling the  user
        to˙determine the roots of an  equation  to  at least
        two decimal place˙accuracy.

        †POLYNOMIAL‡  is  designed  to   run   on   the  Texas
        Instrument˙Professional  Computer   with   one  disk
        drive, 128K RAM, and  3-plane˙graphics  board  or an
        IBM PC with  virtually any of the available˙graphics
        boards. It can accept input from either the keyboard
        or˙the Mouse Systems' PC-Mouse or the  TI  mouse and
        automatically˙senses  the  presence   of   the  8087
        coprocessor   chip.   The   presence   of˙the   8087
        dramatically increases the plotting speed.

        The price is $27.50.
