Find the coordinates of the focus and the vertex, the equations of the directrix and the axis, and length of the latus rectum of the parabola: `(i)x^(2)=16y` (ii)`x^(2)=10y` (iii)`3x^(2)=8y` |

Answer» `(i)F(0,4), O(0,0), y+4=0, x=0,16"units"` `(ii)F(0,(5)/(2)), O(0,0), 2y+5=0, x=0,10"units"` `(iii)F(0,(2)/(3)), O(0,0), 3y+2=0, x=0,(8)/(3)"units"` |
