  # P in parabola equation

It is possible to rewrite this equation using the form $latex {{x}^2}=4py$, where p is a constant used to find the focus and directrix. This corresponds to a parabola with a vertical orientation.

## how do you calculate the focus and directrix from an equation

As per this definition of the eccentricity of the parabola, we have PF = PB (Since e = PF/PB = 1) The coordinates of the focus is F (a,0) and we can use the coordinate distance formula to find its distance from P (x, y) PF = √(x−a)2 You can improve your educational performance by studying regularly and practicing good study habits.

## Conic Sections Parabolas Summary & Analysis

$\displaystyle y = ax^2 + bx + c \,$ To find p, use the following equation. $\displaystyle \frac {1} {4a} = p$ P allows you to find the focus and directrix, of you

## How do I find p in a parabola?

STANDARD EQUATION OF A PARABOLA: Let the vertex be (h, k) and p be the distance between the vertex and the focus and p ≠ 0. (x − h) 2 = 4 p (y − k) vertical axis; directrix is y = k - p (y − k) 2 = 4 p (x − h) horizontal axis; directrix is x = h - p Looking for a little arithmetic help?
