   Extractions: Let's factor the polynomial . We can "pull out" a term Can we do anything else? No, we're done, we have factored the polynomial completely; indeed we have found the four linear (=degree 1) polynomials, which make up f x It just happens that the linear factor x shows up three times. What are the roots of f x )? There are two distinct roots: x =0 and x =-1. It is convenient to say in this situation that the root x =0 has multiplicity 3 , since the term x x -0) shows up three times in the factorization of f x ). Of course, the other root x =-1 is said to have multiplicity 1. We will from now on always count roots according to their multiplicity. So we will say that the polynomial has FOUR roots. Here is another example: How many roots does the polynomial have? The root x =1 has multiplicity 2, the root has multiplicity 3, and the root x =-2 has multiplicity 4. All in all, the polynomial has 9 real roots! A degree 2 polynomial is called a quadratic polynomial. In factoring quadratic polynomials, we naturally encounter three different cases:

   Extractions: The applet on this page is designed for experimenting with the fundamental theorem of algebra, which state that all polynomials with complex coefficients (and hence real as a special case) have a complete set of roots in the complex plane. The applet is designed to impart a geometric understanding of why this is true. It graphs the image in the complex plane, through the entered polynomial, of the circle of radius r. For small r, this is approximately a small circle around the constant term. For very large r, this is approximately a large circle that wraps n times around the origin, where n is the degree of the polynomial. For topological reasons, at some r value in between, the image must pass through the origin. When it does, a root is found. This applet lets you vary the radius and search out these roots. The real and imaginary parts of the polynomial must be entered separately in the function entering panels at the bottom of the applet in this version. There are instructions for how to enter other functions into these applets, but probably you should just try to enter things in and experiment always use * for multiplication, and ^ for powers, and make reasonable guesses about function names, and you may not need the instructions. Also, when you click to go to the radius entering panel, click again after you get there. For reason unbeknownst to me, the canvas on which the radius and such is reported erases itself after being drawn in. But a second click brings it back. The second click makes the exact same graphics calls, so this shouldn't happen. In any case, a second click cures it. If you know how to solve this the source is available on-line please let me know.

   Extractions: Recommend this site Complex numbers are in a sense perfect while there is little doubt that perfect numbers are complex. Starting from the tail, perfect numbers have been studied by the Ancients ( Elements, IX.36 ). Euler (1707-1783) established the form of even perfect numbers. [Conway and Guy, p137] say this: Are there any other perfect numbers? ... All we know about the odd ones is that they must have at least 300 decimal digits and many factors. There probably aren't any! Every one would agree it's rather a complex matter to write down a number in excess of 300 digits. Allowing for a pun, if there are odd perfect numbers they may legitimately be called complex. What about complex numbers in the customary sense? There is at least one good reason to judge them perfect. The Fundamental Theorem of Algebra establishes this reason and is the topic of the discussion below. In the beginning there was counting which gave rise to the natural numbers (or integers ): 1,2,3, and so on. In the space of a few thousand years, the number system kept getting expanded to include fractions, irrational numbers, negative numbers and zero, and eventually complex numbers. Even a cursory glance at the terminology would suggest (except for fractions) the reluctance with which the new numbers have been admitted into the family.

    http://www.cut-the-knot.com/do_you_know/fundamental2.shtml
    
    Extractions: Recommend this site We already discussed the history of the development of the concept of a number. Here I would like to undertake a more formal approach. Thus, in the beginning there was counting. But soon enough people got concerned with equation solving. (If I saw 13 winters and my tribe's law allows a maiden to marry after her 15th winter, how many winters should I wait before being allowed to marry the gorgeous hunter who lives on the other side of the mountain?) The Fundamental Theorem of Algebra is a theorem about equation solving. It states that every polynomial equation over the field of complex numbers of degree higher than 1 has a complex solution. Polynomial equations are in the form P(x) = a n x n + a n-1 x n-1 + ... + a x + a where a n is assumed non-zero (for why to mention it otherwise?), in which case n is called the degree of the polynomial P and of the equation above. a i 's are known coefficients while x is an unknown number. A number a is a solution to the equation P(x) = if substituting a for x renders it identity : P(a) = 0. Coefficients are assumed to belong to a specific set of numbers where we also seek a solution. The polynomial form is very general but often studying P(x) = Q(x) is more convenient.

    Extractions: The Fundamental Theorem of Algebra As remarked before, in the 16th century Cardano noted that the sum of the three solutions to a cubic equation x bx cx d b , the negation of the coefficient of x . By the 17th century the theory of equations had developed so far as to allow Girard (1595-1632) to state a principle of algebra, what we call now "the fundamental theorem of algebra". His formulation, which he didn't prove, also gives a general relation between the n solutions to an n th degree equation and its n coefficients. An n th degree equation can be written in modern notation as x n a x n a n x a n x a n where the coefficients a a n a n , and a n are all constants. Girard said that an n th degree equation admits of n solutions, if you allow all roots and count roots with multiplicity. So, for example, the equation x x x + 1 = has the two solutions 1 and 1. Girard wasn't particularly clear what form his solutions were to have, just that there be n of them: x x x n , and x n Girard gave the relation between the n roots x x x n , and x n and the n coefficients a a n a n , and a n that extends Cardano's remark. First, the sum of the roots

    Extractions: The Fundamental Theorem of Algebra states that every polynomial over the complex numbers has a root. In Nijmegen we have formalised a constructive proof of this theorem in Coq. In this project, we wanted to also set up a library of results (about reals and complex numbers and polynomials) that could be re-used, by us and by others. We have therefore defined an algebraic hierarchy of monoids, groups, rings and so forth that allows to prove generic results and use them for concrete instantiations. In the talk I will briefly outline the FTA project. The main part will consist of an outline of the algebraic hierarchy and its use. This part will contain an explanation of the basic features of Coq.
