CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Fundamental Theorem of Algebra 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.

PRL Seminars Computer Algebra, Theorem Proving, and Types Todd Wilson October 4, 1994 Abstract 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). A discussion of the roles automatic theorem proving might have in these fields. A discussion of types, including

Fundamental theorem of algebra From Wikipedia, the free encyclopedia. The fundamental theorem of algebra (now considered something of a misnomer by many mathematicians) states that every complex polynomial of degree n has exactly n zeroes, counted with multiplicity. More formally, if (where the coefficients a a n can be real or complex numbers), then there exist ( not necessarily distinct) complex numbers z z n such that This shows that the field of complex numbers , unlike the field of real numbers , is algebraically closed n a and the sum of all the roots equals - a n The theorem had been conjectured in the 17th century but could not be proved since the complex numbers had not yet been firmly grounded. The first rigorous proof was given by Carl Friedrich Gauss in 1799. (An almost complete proof had been given earlier by d'Alembert .) Gauss produced several different proofs throughout his lifetime. All proofs of the fundamental theorem necessarily involve some analysis , or more precisely, the concept of continuity of real or complex polynomials. The main difficulty in the proof is to show that every non-constant polynomial has at least one zero. We mention approaches via complex analysis topology , and algebra Find a closed disk D of radius r p z p z r p z D is therefore achieved at some point z in the interior of D p z m p z ) is a holomorphic function in the entire complex plane.

Then F is called a field with respect to these operations if the following properties hold: (i) Closure: For all a,b F the sum a + b and the product a b are uniquely defined and belong to F. (ii) Associative laws: For all a,b,c F, a+(b+c) = (a+b)+c and a (b c) = (a b) c. (iii) Commutative laws: For all a,b F, a+b = b+a and a b = b a. (iv) Distributive laws: For all a,b,c F, a (b+c) = (a b) + (a c) and (a+b) c = (a c) + (b c). (v) Identity elements: The set F contains an additive identity element, denoted by 0, such that for all a F, a+0 = a and 0+a = a. The set F also contains a multiplicative identity element, denoted by 1 (and assumed to be different from 0) such that for all a F

Find a binomial coefficient. Use the Binomial Theorem to expand a binomial raised to a power. Find the rth term of a binomial expansion. Introduction In this tutorial we will mainly be going over the Binomial Theorem. To get to that point I will first be showing you what a factorial is. This is needed to complete problems in this section. This will lead us into the concept of finding a binomial coefficient, which incorporates factorials into it's formula. From there we will put it together into the Binomial Theorem. This theorem gives us a formula that enables us to find the expansion of a binomial raised to a power, without having to multiply the whole thing out. This theorem incorporates the binomial coefficient formula. You will see that everything in this tutorial intertwines. I think that you are ready to move ahead.

Boolean Algebra Introduction Laws of Boolean Algebra Commutative Law Associative Law ... On-line Quiz Introduction The most obvious way to simplify Boolean expressions is to manipulate them in the same way as normal algebraic expressions are manipulated. With regards to logic relations in digital forms, a set of rules for symbolic manipulation is needed in order to solve for the unknowns. A set of rules formulated by the English mathematician George Boole describe certain propositions whose outcome would be either true or false . With regard to digital logic, these rules are used to describe circuits whose state can be either, 1 (true) or (false) . In order to fully understand this, the relation between the AND gate OR gate and NOT gate operations should be appreciated. A number of rules can be derived from these relations as Table 1 demonstrates. P1: X = or X = 1 Table 1: Boolean Postulates Laws of Boolean Algebra Table 2 shows the basic Boolean laws. Note that every law has two expressions, (a) and (b). This is known as duality . These are obtained by changing every AND(.) to OR(+), every OR(+) to AND(.) and all 1's to 0's and vice-versa.

We have x n nx x x k x n Recall in particular a few simple cases: x x x x x x x x x x x x x x x There is a more general form: a b n a n na n-1 b a n-2 b a n-k b k b n with corresponding special cases. Formally this result is only valid for any positive integer n ; in fact it holds appropriately for more general exponents as we shall see in Chapter Another simple algebraic formula that can be useful concerns powers of differences: a b a b a b a b a b a ab b a b a b a a b ab b and in general, we have a n b n a b a n-1 a n-2 b a n-3 b a b n b n-1 Note that we made use of this result when discussing the function after Ex And of course you remember the usual ``completing the square'' trick: ax bx c a x x c a x c Next: Sequences Up: Introduction.

3.4 - Fundamental Theorem of Algebra Each branch of mathematics has its own fundamental theorem(s). If you check out fundamental in the dictionary, you will see that it relates to the foundation or the base or is elementary. Fundamental theorems are important foundations for the rest of the material to follow. Here are some of the fundamental theorems or principles that occur in your text. Fundamental Theorem of Arithmetic (pg 9) Every integer greater than one is either prime or can be expressed as an unique product of prime numbers. Fundamental Theorem of Linear Programming (pg 440) If there is a solution to a linear programming problem, then it will occur at a corner point, or on a line segment between two corner points. Fundamental Counting Principle (pg 574) If there are m ways to do one thing, and n ways to do another, then there are m*n ways of doing both. Fundamental Theorem of Algebra Now, your textbook says at least on zero in the complex number system. That is correct. However, most students forget that reals are also complex numbers, so I will try to spell out real or complex to make things simpler for you.
