Question : 17
Total: 71
Solution:
The given equation of parabola is x 2 = 6y,
which is of the formx 2 = 4ay.
∴ 4a = 6 ⇒ a =
∴ Coordinates of focus are( 0 ,
)
Axis of parabola is x = 0
Equation of the directrix is y =−
⇒ 2y + 3 = 0
Length of latus rectum =
= 6
which is of the form
∴ 4a = 6 ⇒ a =
∴ Coordinates of focus are
Axis of parabola is x = 0
Equation of the directrix is y =
Length of latus rectum =
