Question

Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1.
I tried soving it but I didn't get the answer. Please help

Answer 1

Do you know what the focus and directrix are?

Answer 2

This is not an accurate parabola. But this is what you should understand.

Answer 3

yeah

Answer 4

from directrix shows that equation is along y axis ....
so (0,a)=(0,1)
here a =1
then equation of parabola along y axis is given by
x^2 =4ax
now put a in the above equation and get the answer
x^2 =4x since a =1
this is the equation of parabola
