In each of the following, find the coordinates of the focus, axis of the parabola, the equation of the directrix and the length of the latus rectum.

x2 = 6y


The given equation is y2 = 6y


Here, the coefficient of y is positive.


Hence, the parabola opens upwards.


On comparing this equation with y2 = 4ay, we get,


4a = 6


a =


Thus,


Co-ordinates of the focus = (0,a) =


Since, the given equation involves x2, the axis of the parabola is the y-axis.


Equation of directrix, y =-a, then,


y =


Length of latus rectum = 4a = 6
