Page 220 - This illustration will serve to introduce the definition of the next section. 476. Limit of a Variable. When the successive values of a variable approach a certain constant number so that the difference between the constant and the variable becomes and remains less than any assigned positive number, however small, then the constant is called the limit of the variable. 477. The statement "x approaches the limit a," where x is a variable and a is a constant, is sometimes written x = a, the symbol =...

Page 1 - As long as algebra and geometry proceeded along separate paths, their advance was slow and their applications limited. But when these sciences joined company they drew from each other fresh vitality and thenceforward marched on at a rapid pace towards perfection.
Page 95 - A point moves so that the sum of the squares of its distances from the points (0, 0), (1, 0) is constant.
Page 134 - The parabola is the locus of a point whose distance from a fixed point, the focus, is always equal to its distance from a fixed line, the directrix.
Page 117 - By definition [§ 69], the ellipse is the locus of a point whose distance from a fixed point, the focus, divided by its distance from a fixed line, the directrix, is a constant e, less than 1. Let F be the focus ,' and SR the directrix. Through F take А' я с A tsFD perpendicular to SR at D. There is a point A between F and D such that FA/AD = e.
