Question

wht is ordinate in parabola ??? expain with examples???​

Answer 1

Answer:

What us double ordinate in parabola?

Step-by-step explanation:

Any chord perpendicular to the axis of the parabola is called its double ordinate.

Example:- Find an equation of the parabola having its focus at (0,–3) and as its directrix on the line y=3.

Solution: Since the focus is on the Y-axis and is also below the directrix, the parabola opens downward, and a= –3. Hence the equation of the parabola is x2=–12y. The length of the latus rectum is |4(–3)|=12.
