Module for Graeffe's Method Background We use the following important result from the study of the theory of equations. Theorem ( Vieta's Formulas Consider a polynomial of of degree n with roots Let be the elementary symmetric function or symmetric polynomial for the variables then Moreover, we have the important identities relating the coefficients of for Exploration Graeffe's Method Separated Roots If the roots of are widely separated in magnitude, then they can be approximated using ratios of the coefficients of . This is the heart of the Graeffe method. Theorem (Separated Real Roots). If is a polynomial with real roots that are widely separated in magnitude then for Exploration Graeffe's Method Example 1. Approximate the roots of the following polynomials using the separated root theorem. 1 (a). 1 (b). 1 (c). Solution 1. Graeffe Root Squaring Method The root-finding method was popular in the 19th and 20th centuries. It was invented independently by Germinal Pierre Dandelin (1794-1847), and

De stelling van Dandelin Germinal Pierre Dandelin (1794-1847, Le Bourget) werd geboren in Frankrijk, maar wordt toch beschouwd als Belgisch wiskundige; hij bracht het grootste deel van zijn leven in België door (zijn moeder was Belgische), maar zeker ook omdat hij enige tijd mijnbouwkunde doceerde aan de universiteit van Luik. Dandelin's eerste wiskundige belangstelling gold de meetkunde. In 1822 ontdekte hij een belangrijke stelling, naar hem genoemd, over het verband tussen de doorsnede van een vlak en een kegel, en binnen die kegel beschreven bollen, de bollen van Dandelin De stelling van Dandelin en de genoemde bollen worden behandeld in de paragraaf 2 (ellips), paragraaf 3 (parabool) en paragraaf 4 (hyperbool). figuur 1 In figuur 1 is een doorsnede getekend van een kegel met het vlak van tekening T (diagonaalvlak). a is de as van de kegel en b is een beschrijvende. a is de halve tophoek van de kegel. c is de snijlijn van een vlak door O loodrecht op T.

51. Mathematics At West Point In The Early Twentieth Century germinal Pierre dandelin (17941847) discovered his proof using spheres in a coneto prove that a plane intersecting a cone is a conic. That was in 1822, http://www.dean.usma.edu/math/people/rickey/dms/talks/2004-02-19-Early20th-PASHo

Mathematics at West Point in the Early Twentieth Century (a very preliminary report) V. Frederick Rickey Department of Mathematical Sciences United States Military Academy West Point, NY 10996 fred-rickey@usma.edu Philadelphia Area Seminar on the History of Mathematics Villanova University, February 19, 2004. The United States Military Academy celebrated its centennial in 1902 but was it a vibrant intellectual center or a school with a hundred years of tradition unimpeded by progress? Since the study of mathematics occupied a substantial portion of the education of every graduate, this motivates us to look at all aspects of the department of mathematics: Who were the faculty? What was their education and experience? What was the curriculum? Which textbooks were used? How were the classes conducted? How did the department interact with the national mathematical community? How did world events impact the department? In terms of leadership, during the first half of the twentieth-century the history of the Department of Mathematics is rather simple because the department had only four Department Heads. Wright P. Edgerton served from 1898 to his death in 1904 and was succeeded by Charles P. Echols who served from 1904 until 1931 when he retired at the mandatory retirement age of 64. Because of that long term, he will be the major player in our story. Harris Jones took up the post in 1931 and served until 1947 when he became Dean of the Academic Board. Finally William W. Bessell, Jr., was Head from 1947 until 1959 when he became Dean.

52. Pascal S Theorem is due to the nineteenth century Belgian mathematician germinal dandelin. dandelin s threedimensional proof of Pascal s Theorem (and its dual, http://www.math.ubc.ca/~cass/courses/java/pascal/pascal.html

Pascal's Theorem Pascal's Theorem asserts: If one is given six points on a conic section and makes a hexagon out of them in an arbitrary order, then the points of intersection of opposite sides of this hexagon will all lie on a single line. Pascal's configuration Move the points by dragging them. Reload the page to restore the initial configuration. There are many proofs known, but one of the most attractive is due to the nineteenth century Belgian mathematician Germinal Dandelin. It has the virtue of being perhaps the most geometric in flavour. This proof has much in common with the best known proof of Desargues' Theorem , in that it can be interpreted in terms of a three-dimensional configuration. Both Desargues' Theorem and Pascal's Theorem assert that three points defined as the intersections of certain pairs of lines in a configuration are collinear. One very natural way to see that three points in a plane are collinear is to find a plane other than the given one containing the three given points, which must all therefore lie on the intersection of two planes. For Desargues' Theorem, this plane is simple to construct, for Pascal's not quite so simple. The three-dimensional proof of Pascal's Theorem is now well known, but seems to have originated with Dandelin.
