Why it is parabolic?
Give me an accurate answer.

The gradient is nothing but a slope. And the best way to join 2 gradients using a vertical curve is obviously using a parabolic one.

Because rate of change of gradient in parabolic curve is constant.
So generally used parabolic type of curve.

The main design criteria in a vertical curve is headlight sight distance. So I think it may be circular as the sight distance available at each point is same.

A rising gradient of 1 in 40 is to be connected with a falling gradient of 1 in 75 by means of a vertical equal tangent parabolic curve 400 m in length. The reduce level at the intersection point of the tangent is 26.850.
Calculate:
(1) The rate of change of grade.
(2) The reduced levels at the beginning and end tangent points.

All other shapes are 2D. But, to connect two gradients it should be a parabolic which can be drawn in 3D.

How it will be parabolic?
