...whole line. 5. Given the base, area, and one of the angles at the base, construct the triangle. 6. Find the locus of a point which moves so that the sum of the squares of its distance from four given points is constant. On the Quadrature of a Rectilineal...

...given point parallel to a given plane ? parallel to a given line ? in. ANALYTIC GEOMETRY. 1. Determine the locus of a point which moves so that the sum of the Hquares of its distances from two fixed points is constant. Also determine the locus, changing...

...determine whether the straight line x + У = 2 +-/2 is a tangent or not. 17. Find the locus of a point, P, which moves so that the sum of its distances from two fixed points, A and B, is constant. 1870. July 19th. — Examiners, — Prof. HJS SMITH, MA, FRS, and Prof. SYLVESTER,...

...II. THE ELLIPSE. Definitions. 9. An ellipse is a plane curve that may be generated by a point, moving so that the sum of its distances from two fixed points is equal to a given line. The moving point is called the generatrix; the fixed points are foci ; the straight...

...fixed points. In what case does the conic degenerate into two intersecting straight lines ? 45. Find the locus of a point which moves so that the sum of the squares on the tangents drawn from it to the ellipse, -—- - + —jf = 1, is constant. X a v'...

...of the perpendiculars from any other point P, will bisect OP. [Such a polygon has the property that the locus of a point, which moves so that the sum of the squares on its distances from the sides is constant, is a circle.] 2254. The limiting position...
