Question

Please help I give medal and fan!!
Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1.

Answer 1

I really need someone to try to explain it to me in English D: I tried using the lesson and googling but it still seriously does not make any sense.

Answer 2

hey are you still here?

Me neither D:

Answer 14

Hey sorry I was having some loading issues.

Answer 15

I kinda like to start by drawing the picture first. Do you know how to do that?

Answer 16

nope

Answer 17

D;

Answer 18

Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1.


(0,1) is an ordered pair
y=-1 is a line
I'm sure you have know trouble graphing those. So let's start by putting those on a graph.

Answer 19

now the vertex should fall half way in between the focus and the directrix
so we actually already know the vertex is what?

Answer 20

Sorry in a sec open study is loading forever waiting for the graph to show up

Answer 21

well anyways...
you can find the equation by equating the distance between the Focus and a point on the parabola (call it (x,y)) with the distance between the point on the directrix (x,-1) and (x,y)
