Variation and Polynomial Equations It focuses on the topics of variation and polynomial equations and includes direct variation and proportion, inverse and joint variation, dividing polynomials, synthetic division, the remainder and factor theorems, conjugate root theorem, Descartes’ rule of signs, finding rational roots, approximating irrational roots, and linear interpolation. Lecture: Teacher introduces the conjugate root theorem and Descartes’ Rule of Signs and shows some examples of how they are used. Descartes’ rule of signs fives information about the numbers of positive and negative real roots. filebox.vt.edu /users/tlysek/tlysekunitplan.htm   (3160 words)

content_1.doc One of the simplest methods to finding rational zeros involves a combination of educated guessing via the “rational zeros” theorem and Descartes’ rule of signs, synthetic or long division, and trial and error. Descartes’ rule of signs allows us to determine the possible number of positive and negative real zeros of a polynomial. In order to use this theorem, we need a polynomial with integer coefficients. www.math.tamu.edu /~axelson/content_1.doc   (1356 words)

Isaac Newton (1642 - 1727) The most interesting theorem contained in the work is his attempt to find a rule (analogous to that of Descartes for real roots) by which the number of imaginary roots of an equation can be determined. He begins with some general theorems, and classifies curves according as their equations are algebraical or transcendental; the former being cut by a straight line in a number of points (real or imaginary) equal to the degree of the curve, the latter being cut by a straight line in an infinite number of points. When he discovered the theorems that form the first three sections of book I, when he gave them in his lectures of 1684, he was unaware that the sun and earth exerted their attractions as if they were but points. www.maths.tcd.ie /pub/HistMath/People/Newton/RouseBall/RB_Newton.html   (8709 words)

Political Film Society - The Thirteenth Floor When the film begins, Descartes is quoted, "I think, therefore I am." When the film ends, filmviewers are presumably to leave the cinema asking whether they are really exercising free will or are instead programmed by an external force in an endless reincarnation simulation. However, the dialog of the film deals with mundane rather than profound matters, and the film offers only 100 minutes of escape that are unlikely to bring about Cartesian self-exploration. Jane Fuller (played by Gretchen Mol), Hannon’s daughter, tries to persuade Hall not to destroy the simulation by informing him that he is playing a role in 1999 that is itself a simulation. www.geocities.com /~polfilms/thirteenthfloor.html   (349 words)

Classics in the History of Psychology -- Reading Suggestions for History of Psychology Courses In Descartes' final book, The Passions of the Soul (1649), he outlines the relation, as he saw it, between the mind and body, and presents his theory of the emotions. Read through the example in which the slave boy is shown to innately understand the Pythagorean Theorem, and end where Socrates concludes "And if the truth of all things always existed in the soul, then the soul is immortal" (86b) (about 11 pp.). Biological and theological theories of the mind and soul were closely connected during the Middle Ages. psychclassics.yorku.ca /suggestions.htm   (349 words)

DESCARTES, RENE (1596-1650) - Online Information article about DESCARTES, RENE (1596-1650) In another question connected with this, the problem of drawing tangents to any curve, Descartes was drawn into a controversy with Pierre (de) Fermat (16011663), Gilles Persone de Roberval (16021675), and Girard Desargues (15931661). And the salons of Mme de Sevigne, of her daughter Mme de Grignan, and of the duchesse de Maine for a while gave the questions of philosophy a place among the topics of polite society, and furnished to Moliere the occasion of his Femmes savantes. The Chateau of the duo de Luynes, the translator of the Meditations, was the home of a Cartesian club, that discussed the questions of automatism and of the composition of the sun from filings and parings, and rivalled Port Royal in its vivisections. encyclopedia.jrank.org /DEM_DIO/DESCARTES_RENE_1596_1650_.html   (349 words)

Feature Column Descartes' Theorem is a very lovely result in its own right, and in 3 dimensions it is equivalent to Euler's polyhedral formula. The fundamental theorem that is used directly or indirectly in a proof of the Euler polyhedra formula for graphs depends on the Jordan Curve theorem, which states that any simple closed curve divides the plane into three sets, those points on the curve, those inside the curve, and those outside the curve. Ironically, this quintessentially combinatorial theorem was given a metric proof by Legendre. www.ams.org /featurecolumn/archive/eulers-formula.html   (349 words)

Search Results for Klein His work on the foundations of geometry led him to publish Demonstration of Descartes's theorem and Euler's theorem in the Annals of Mathematics in 1885, the year after he arrived at Austin, and then, in the same journal, Klein's Evanston lectures in 1893. A special case of Emmy Noether's theorem was written down by Weyl in 1917 when he derived from it identities which, it was later realised, had been independently discovered by Ricci in 1889 and by Bianchi (a pupil of Klein) in 1902. Klein initiated a correspondence with Poincare, and soon a friendly rivalry ensued as both sought to formulate and prove a grand uniformization theorem that would serve as a capstone to this theory. www-history.mcs.st-and.ac.uk /~history/Search/historysearch.cgi?SUGGESTION=Klein&CONTEXT=1   (10790 words)

Math Forum - Ask Dr. Math Date: 08/28/98 at 01:34:57 From: Doctor Pat Subject: Re: Rational zeros Bill (and son), This is called the Rational Root Theorem, and I think it is usually credited to Descartes. According to the Rational Root Theorem, the rational root must be a fraction whose numerator is a factor of a(0) and whose denominator is a factor of a(n); but they can be positive or negative. The theorem goes as follows: Let p be any polynomial function with integer coefficients. mathforum.org /library/drmath/view/56425.html   (1060 words)

Descartes 3 The first theorem is the one best remembered today; his second theorem is an exact rediscovery of Descartes' theorem from some 130 years before. In Euler's papers he states two theorems, describing them as equally important, and emphasizing that they are completely equivalent. As Euler explains, the link between these two theorems is the fact from plane geometry that in a polygon of n sides, the sum of the angles is (n-2) www.math.sunysb.edu /%7Etony/whatsnew/column/descartes-0899/descartes3.html   (488 words)

Descartes 7 Finally, for Descartes the distinction between a vertex and the measure of the (planar or solid) angle at that vertex was not explicit; the lack of this distinction, probably, kept him from the combinatorial version of his theorem that Euler derived. Moreover negative curvature would not have seemed a natural concept: at the beginning of Descartes' career (he was 24 in 1620) he was reluctant to consider negative numbers at all. Nevertheless his Lost Theorem, now recovered, remains as indelible evidence of the geometrical power of this intellectual giant. www.math.sunysb.edu /~tony/whatsnew/column/descartes-0899/descartes7.html   (361 words)

ImmInst.org -> Pascal's Wager: Is God a safe bet? Among the contemporaries of Descartes none displayed greater natural genius than Pascal, but his mathematical reputation rests more on what he might have done than on what he actually effected, as during a considerable part of his life he deemed it his duty to devote his whole time to religious exercises. Pascal's project, then, is radically different: he seeks to provide prudential reasons for believing in God. Pascal is apparently unimpressed by such attempted justifications of theism: "Endeavour... www.imminst.org /forum/index.php?act=ST&f=63&t=1199&s=   (5009 words)

iqexpand.com A discrete analog of the Gauss-Bonnet theorem is Descartes' theorem that the "total defect" of a polyhedron, measured in full circles, is the Euler characteristic of the polyhedron; see defect (geometry). For closed Riemannian manifolds, the Euler characteristic can also be found by integrating the curvature--see the Gauss-Bonnet theorem for two-dimensional case and generalized Gauss-Bonnet theorem for general case. The concept of Euler characteristic of a bounded finite poset is another generalization, important in combinatorics. euler_characteristic.iqexpand.com   (1012 words)
