1) Find the equation of a circle which passes through the origin and cuts off intercepts -2 and 3 from the axis and the y-axis respectively. (Solution: x2 + y2 + 2x -3y)

2) Find the equation of the circle passing through the points – (0,0)(5,0) and (3,3). (Solution: x2 + y2 – 5x -y =0), centre (5/2 , ½) and radius =  √ 26/2).

3) If the distance between the foci of a hyperbola is 16 and eccentricity is  √ 2, then obtain its equation. (Solution: x2 – y2 =32)

4) If a latus rectum of an ellipse subtends a right angle at the centre of the ellipse, then write the eccentricity of the ellipse. (Solution:  (√ 5 – 1) / 2)

5) Find the equation of the ellipse whose foci are (4,0) and (-4,0), eccentricity = ⅓. (Solution: x2 / 9 + y2/8 = 16)

6) Write the equation of the parabola whose vertex is at (-3,0) and the directrix is (x + 5 ) = 0. (Solution: y2 = 8(x + 3))

7) AB is a double ordinate of a parabola y2 = 4px. Find the locus of its points of trisection. (Solution: 9y2 =4px)

8) Find the equation of the parabola whose focus is (1, -1) and whose vertex is (2,1). Also, find its axis and latus- rectum). (Solution: 4 √ 5).

9) Find the equation of the circle which circumscribes the triangle formed by the lines x = 0, y = 0 and lx +my = 1. (Solution: x2 + y2 – (1/l)x – (1/m)y = 0)

10) Prove that the points  (9,1) ( 7,9) (-2, 12) and (6,10) are concyclic.
