Question
In the following, find the co-ordinates of the focus, axis of the parabola, the equation of the directrix and length of the latus rectum.
Solution
It is the equation of parabola in the standard form and open towards the right.
Comparing with we have 4a = 10
∴ The co-ordinates of the focus S are (a, 0)
The equation of the axis of the parabola is y = 0 (x - axis).
The equation of directrix is x + a = 0 or
The length of latus rectum =
The equation of the axis of the parabola is y = 0 (x - axis).
The equation of directrix is x + a = 0 or
The length of latus rectum =
