EQUATION - LoveToKnow Article on EQUATION   (Site not responding. Last check: 2007-10-09) Equations of the first degree are called simple or linear; of the second, quadratic; of the third, cubic; of the fourth, biquadratic; of the fifth, quintic, and so on. Quadratic equations arose in the Greek investigations in the doctrine of proportion, and although they were presented and solved in a geometrical form, the methods employed have no relation to the generalized conception of algebraic geometry which represents a curve by an equation and vice versa. Pure cubic equations are therefore of the form xf=r; and hence it appears that a value of the simple power of the unknown quantity may always be found without difficulty, by extracting the cube root of each side of the equation. www.1911encyclopedia.org /E/EQ/EQUATION.htm   (12081 words)

Group Theory Leonard Euler (1707-1783) came at space curves through a system of parametric equations or equations that could be used to describe a curve in the cartesian coordinate system. From Novy, the work that Lagrange did with reduced equations and permutation of roots failed to assist him in the answer to the question as to whether the fifth degree equation was solvable or not. Cauchy was the first to employ a permutation in the same way that we use it today. mathtabriz.tripod.com /mathtabriz/id4.html   (3911 words)

Cauchys formula, which represents the fact very well throughout most of the visible spectrum, = A + BA so that (10), For simplicity, suppose that the lower surface is plane (y=o), and that the approximate equation of the upper surface is y=a+bxf, a being thus the least distance between the plates.

ugander.com/johan What got me thinking enough to write this piece is the equation for the linear strain at a given angle, phi. Don't bother studying the equation, what I want to discuss (but won't present in full) is the "proof" of this relationship. Also, the sheer multitude of equations in material mechanics means that I can't keep track of these approximations, and that gives it all a general plug-and-chug feeling. www.ugander.com /johan/2005/09/my-thoughts-precisely.html   (853 words)
