1.	Find the equation of the ellipse in the following cases: (i) focus is (0,1), directrix is x+y=0 and e=12. (ii) focus is (-1,1), directrix is x-y+3=0 and e=12. (iii) focus is (-2,3), directrix is 2x+3y+4=0 and e=45. (iv) focus is (1,2), directrix is 3x+4y-5=0 and e=12.
Answer» Find the equation of the ellipse in the following cases: (i) focus is (0,1), directrix is x+y=0 and $e = \frac{1}{2}$ . (ii) focus is (-1,1), directrix is x-y+3=0 and $e = \frac{1}{2}$ . (iii) focus is (-2,3), directrix is 2x+3y+4=0 and $e = \frac{4}{5}$ . (iv) focus is (1,2), directrix is 3x+4y-5=0 and $e = \frac{1}{2}$ .
