http://en.wikipedia.org/wiki/Fundamental_theorem_of_algebra

Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search In mathematics , the fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root . Equivalently, the field of complex numbers is algebraically closed Sometimes, this theorem is stated as: every non-zero single-variable polynomial with complex coefficients has exactly as many complex roots as its degree, if each root is counted up to its multiplicity . Although this at first appears to be a stronger statement, it is a direct consequence of the other form of the theorem, through the use of successive polynomial division by linear factors. In spite of its name, there is no purely algebraic proof of the theorem, since any proof must use the completeness of the reals (or some other equivalent formulation of completeness), which is not an algebraic concept. Additionally, it is not fundamental for modern algebra ; its name was given at a time in which algebra was mainly about solving polynomial equations with real or complex coefficients.

3. DeMorgan's Theorems : BOOLEAN ALGEBRA
DeMorgan s Theorems. A mathematician named DeMorgan developed a pair of important rules regarding group complementation in Boolean algebra.

Extractions: var addthis_pub = 'GFYGCMPH6Z132X8G'; Volume IV - Digital BOOLEAN ALGEBRA A mathematician named DeMorgan developed a pair of important rules regarding group complementation in Boolean algebra. By group complementation, I'm referring to the complement of a group of terms, represented by a long bar over more than one variable. You should recall from the chapter on logic gates that inverting all inputs to a gate reverses that gate's essential function from AND to OR, or vice versa, and also inverts the output. So, an OR gate with all inputs inverted (a Negative-OR gate) behaves the same as a NAND gate, and an AND gate with all inputs inverted (a Negative-AND gate) behaves the same as a NOR gate. DeMorgan's theorems state the same equivalence in "backward" form: that inverting the output of any gate results in the same function as the opposite type of gate (AND vs. OR) with inverted inputs: A long bar extending over the term AB acts as a grouping symbol, and as such is entirely different from the product of A and B independently inverted. In other words, (AB)' is not equal to A'B'. Because the "prime" symbol (') cannot be stretched over two variables like a bar can, we are forced to use parentheses to make it apply to the whole term AB in the previous sentence. A bar, however, acts as its own grouping symbol when stretched over more than one variable. This has profound impact on how Boolean expressions are evaluated and reduced, as we shall see.

Extractions: Draw the schematic diagram for the digital circuit to be analyzed. Carefully build this circuit on a breadboard or other convenient medium. Check the accuracy of the circuit's construction, following each wire to each connection point, and verifying these elements one-by-one on the diagram. Analyze the circuit, determining all output logic states for given input conditions. Carefully measure those logic states, to verify the accuracy of your analysis. If there are any errors, carefully check your circuit's construction against the diagram, then carefully re-analyze the circuit and re-measure.

6. The Fundamental Theorem Of Algebra
What does The Fundamental Theorem of Algebra not tell us? It is not constructive , that is, it does not tell us how to factor a polynomial completely!
http://www.sosmath.com/algebra/factor/fac04/fac04.html

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: October 4, 1994 Many computations a mathematician performs can be described in "algebraic" terms, that is, as dealing with various symbolic entities that are combined in restricted ways and are subject to laws (e.g., equations) specifying which combinations are equivalent. The term "computer algebra", as it appears in my title, has this general sense (as opposed to the more restrictive sense of "computational commutative algebra"), and my talk will discuss this subject and its relation to automatic theorem proving and type theory. In more detail, the talk will consist of the following: A survey of examples of computer algebra drawn from several areas of mathematics, including commutative algebra and algebraic geometry, invariant theory, (algebraic) number theory, group theory, Lie algebra, combinatorics, algebraic topology, and analysis (scientific computation).

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

http://www.mathpages.com/home/kmath056/kmath056.htm

Extractions: The Fundamental Theorem of Algebra There is a Russian emissary here whose two young and intellectually gifted daughters I was supposed to instruct in mathematics and astronomy. I was, however, too late, and a French émigré obtained the position.                   C. F. Gauss, 1798 Gauss’s doctoral dissertation, published in 1799, provided the first genuine proof of the fact that every polynomial (in one variable) with real coefficients can be factored into linear and/or quadratic factors. Imaginary and complex numbers were not widely accepted at that time, but today this proposition – traditionally called the fundamental theorem of algebra - is usually expressed by saying that every polynomial of degree n possesses n complex roots, counting multiplicities. Although Gauss’s 1799 proof focused on polynomials with real coefficients, it isn’t difficult to extend the result to polynomials with complex coefficients as well. By modern standards, Gauss’s proof was not rigorously complete, since he relied on the continuity of certain curves, but it was a major improvement over all previous attempts at a proof. Only about a third of Gauss’s dissertation was actually taken up by the proof. The rest consisted of a rather frank assessment of the previously claimed proofs of this proposition by D’Alembert, Euler, Legendre, Lagrange, and others. Gauss explained that all their attempts were fallacious, and indeed that they didn’t even address the real problem. They all implicitly assumed the existence of the roots, and just sought to determine the form of those roots. Gauss pointed out that the real task was to prove the
