## Parabola

In mathematics, A Parabola is a U-shaped plane curve with mirror symmetry. A parabola is defined as the locus of points in that plane that are at equal distance from both the directrix and the focus of the parabola.

Coming to the equation of parabola,

If a parabola has a vertical axis, the standard form of the equation of the parabola is:

(x – h)2 = 4p(y – k), where p≠ 0.

The vertex of this parabola is at (h, k). The focus is at (h, k + p). The directrix is the line y = kp. The axis is the line x = h

f a parabola has a horizontal axis, the standard form of the equation of the parabola is this:

(y – k)2 = 4p(x – h), where p≠ 0.

The vertex of this parabola is at (h, k). The focus is at (h + p, k). The directrix is the line x = hp
