A parable is a succinct, didactic story, in prose or verse, that illustrates one or more instructive lessons or principles.It differs from a fable in that fables employ animals, plants, inanimate objects, or forces of nature as characters, whereas parables have human characters. [1]
The parabola is a member of the family of conic sections. In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves.

Parabolic usually refers to something in a shape of a parabola, but may also refer to a parable. Parabolic may refer to: In mathematics: In elementary mathematics, especially elementary geometry: Parabolic coordinates; Parabolic cylindrical coordinates; parabolic Möbius transformation; Parabolic geometry (disambiguation) Parabolic spiral ...
The name of the magazine is explained by the editors as follows: The parabola represents the epitome of a quest. It is the metaphorical journey to a particular point, and then back home, along a similar path perhaps, but in a different direction, after which the traveler is essentially, irrevocably changed.
A parabolic segment is the region bounded by a parabola and line. To find the area of a parabolic segment, Archimedes considers a certain inscribed triangle. The base of this triangle is the given chord of the parabola, and the third vertex is the point on the parabola such that the tangent to the parabola at that point is parallel to the chord.
As an encyclopaedia, the authors set out to create a scholarly work, but accessible to the non-expert, designed to be. a Manual of Sacred Literature for the use of Ministers, Students, General Readers, and Sunday School Libraries, so complete in itself that no other work will be necessary for ordinary purposes of reference in these branches of knowledge.
While a parabolic arch may resemble a catenary arch, a parabola is a quadratic function while a catenary is the hyperbolic cosine, cosh(x), a sum of two exponential functions. One parabola is f(x) = x 2 + 3x − 1, and hyperbolic cosine is cosh(x) = e x + e −x / 2 . The curves are unrelated.
