Show that whatever be the value of m, the straight line y = mx +, / { (a + bm?)/ab } touches the conic ax"- + by 2 = 1. 10. A straight line moves so that (i) the product, (ii) the sum, of the squares of the perpendiculars drawn to it from two fixed points (c, 0), ( c, 0) is constant ; show that in each case the envelope is a central conic. 11. Show that the envelope of the circles described on the central radii of an ellipse as diameters is 12. The envelope of the ellipses (x - a) 2 /a 2 + (y -... /3) 2 //; 2 = 1 when the parameters a, /3 are connected by the equation is the ellipse A' 2 /a 2 + ?/ 2 /& 2 = 4. State the problem in geometrical language. 13. Show that the envelope of the family of straight lines ax sec a by cosec a = a 2 b- is the curve 14. If in Fig. 82 OZ=p, show that the equations of the tangent and normal at P are d'f) x sin > y cos (f> =p (i) ; x cos +y sin (/> = |3hr (ii), and show, from (ii), that ZP = Consider the curve as the envelope of its tangents. 15.
