Lambert, Preston Albert, 1862-1925 · New York, Macmillan · leaf 157
iven Lines Let « = 0 and b = 0 represent two straight lines intersectedhy the straight line c = 0. The equation ab — kc = 0 repre-sents a conic section tan-gent to the lines a = 0,6 = 0 at the points of inter-section of c — 0. For theequation ab — kc = 0 is ofthe second degree, and thepoints of… … SECOND DEGliEK EQUATION 143 ab — kc- — 0. Since k is arbitrary, an infinite number of conicsections can be drawn tangent to the given lines at the givenpoints. The equation of a conic section tangent to the lines x = (),y = 0 lit the i)oints (a, 0), (0, h) is a b Kxy = 0. (1) The points of…
