Write equation of parabola given focus and directrix calculator

   For:
      vertex: (h, k)
      focus: (x1, y1)

• The Parobola Equation in Vertex Form is:
     (X-h)2 = 4a(Y-k);    ( a = √(h-x1) * (h-x1) + (k - y1) * (k-y1) )

• The Parobola Equation in Standard Form is:
     Y = (1/4a)X2 - (h/2a)X + (k + h2/4a);    ( a = √(h-x1) * (h-x1) + (k - y1) * (k-y1) )

What is Meant by Parabola?

In Maths, a parabola is one of the types of conic sections. A parabola is a symmetrical plane curve which is formed by the intersection of a right circular cone with a plane surface. It is a U- shaped curve with specific properties. In short, a parabola is a curve such that any point on the curve is at equal distance from a fixed point called locus and a fixed straight line called the directrix. The simplest form of parabola equation is given by y = x2.

What is parabola using focus and Directrix?

What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
