Pāgina 41 - Find the locus of a point, the distances of which from two given straight lines have a fixed ratio. 143. Find the locus of a point which moves so that the sum of its distances from two vertices of an equilateral triangle shall equal its distance from the third.
Pāgina 17 - The sum of the squares of the four sides of any quadrilateral is equal to the sum of the squares of the diagonals plus four times the square of the line joining the mid-points of the diagonals.
Pāgina 38 - Show that the locus of a point which moves so that the sum of its distances from two h'xed straight lines is constant is a straight line.
Pāgina 184 - Find the locus of a point such that the sum of the squares of its distances from two fixed points shall be equivalent to the square of the distance between the fixed points.
Pāgina 131 - The locus of the middle points of a system of parallel chords in a parabola is called a diameter.
Pāgina 130 - Shew that the locus of the middle points of a system of parallel chords of a parabola is a straight line parallel to the axis of the parabola.
Pāgina 40 - PF'/PH'= e, by the definition of the curve. Furthermore :J (b) \PF—PF'\=2a. In fact, the hyperbola is often defined as the locus of a point which moves so that the difference of its distances from two fixed points is constant.
