Parabola is like the curve y² = 4 a x .

It is the locus of points which are equidistant from a point called the FOCUS of parabola and a line called DIRECTRIX. The line joining its vertex and focus point is called its axis. The line directrix is perpendicular to the axis.

For the above parabola, y² = 4 a x:

(0,0) is the vertex. (a, 0) is the focus point. Directrix line is x + a = 0

Generally, in Physics: The path of a stone thrown in to the air at an angle is a parabola. Its equation in 2-dimensions is the 2nd order equation in x and y, with some conditions satisfied.

*is to first find its vertex, focus, and directrix. Then locate or move point which is equidistant from these two. Start drawing at the vertex and move away from it.***The way to draw the parabola****Draw vertex. Choose a point on directrix P'. Join FP'. Find mid-point Q. It lies on y axis. Draw perpendicular bisector for P'F. Draw a horizontal line from P' to meet the bisector at P. P lies on the PARABOLA.***In detail:*Generally, in Physics: The path of a stone thrown in to the air at an angle is a parabola.
