Página 300 - Hyperbola is the locus of a point which moves so that its distance from a fixed point, called the focus, bears a constant ratio, which is greater than unity, to its distance from a fixed straight line, called the directrix.

Página 45 - K, x and y instead of a and (i, we have for the equation of its locus (3) Through a fixed point O any straight line is drawn meeting two given parallel straight lines in P and Q; through P and Q straight lines are drawn in fixed directions, meeting in B : prove that the locus of E is a straight line.

Página 268 - D' is a right angle, and the angle DPF = DPD', and PF = PD', .-. DFP is a right angle. In like manner, DFP' is a right angle ; hence, first, the part of the tangent intercepted between the point of contact and the directrix, subtends a right angle at the focus ; second, the line joining the points of contact of perpendicular tangents always passes through thefocut.
