Polynomial Plotter

The software will plot the graph of any polynomial of degree 6 or less with real coefficients in a qualitative way, that is, without any reference to the location of various points on the axes. In this form the plotter is very useful as a visual complement to first year science or engineering students in their graph-sketching pursuits as they can detect the changes in concavity, inflection points, critical points on the graphs. This allows one to gain insight drawn from theoretical calculations., without having to worry about numerical accuracy to 9 decimal places!

The 3n+1 problem

One of the big problems in an area of mathematics called Number Theory is commonly called The 3n+1 Problem . Well, what is it? Let's say you start with a positive number, any number. If the number is odd (like 5, 7,...) multiply it by three and then add 1 and if this number is even divide it by two and keep doing doing this as long as you can! Here's an example. Claim: this sequence of numbers always ends with 1 regardless of the choice of the original number!!! If you want to try and see how this program works, go here The Problem is: No one on this planet knows why this sequence of numbers HAS to end with 1!!

Full-version programs

The full version of the Polynomial Plotter (above) can be found here.This MS-Windows program will accept any standard function for input and return its graph on a prescribed interval. It will also find its roots and extrema and calculate function values as well. A README file is included which should be read! Platforms include MS-Windows 3.1, 3.1.1, 95, 98 and NT 4.0 (all on the same executable). For sample screenshots and help file click here.
