good to know!
The focal point to the vertex = directrix to vertex Thaaaaanks Unicorny.
I know the directrix is equidistant from the vertex as the focus is. I just don't know how to find it!
Unicorny, that didn't answer my question.
Yes. And the directrix and lattus rectum?
If I did that, my teach would fail me.
Mathematically.
I knew that... i meant, how do I find it to graph it?
>.>
And how do you figure out what it is?
I knoooooowwwwwwwww! Fine. -.- In the parabola equation (y-k)^2 = 4p (x-h), what does the 4p mean and what does it do to a parabola?
Sure. And what does it do to a parabola?
