PARABOLAS Meaning and
Definition
-
Parabolas are a type of curved shape that is common in mathematics and physics. Derived from the Greek word "parabole," meaning "comparison," a parabola is defined as a symmetric curve formed by the intersection of a cone with a plane parallel to its side. It is a conic section, meaning it is obtained by intersecting a cone with a plane.
In simpler terms, a parabola is a U-shaped curve that open upwards or downwards. Its points are equidistant from both the focus and the directrix. The focus is a fixed point inside the curve, while the directrix is a straight line outside the curve. The distance from any point on the parabola to the focus is equal to the distance from that same point to the directrix.
Parabolas have numerous applications in mathematics, physics, and engineering. They are often used to model the shapes of satellite dishes, antennas, and reflectors, as well as the trajectories of projectiles. In algebra, the equation of a parabola can be expressed in terms of the Cartesian coordinates (x, y) using a quadratic equation. This equation can be used to determine the vertex, focus, directrix, and other key properties of the parabola.
Overall, parabolas are a fundamental geometric shape in mathematics, known for their unique symmetrical curvature. They are an essential concept in calculus, geometry, and algebra.

Etymology of PARABOLAS
The word "parabolas" has its etymology in Greek. It is derived from the Greek word "parabole" which means "comparison" or "analogy". In mathematics, a parabola is a curve formed by the intersection of a cone and a plane parallel to its side, which can be described by a quadratic equation. The term became commonly used in English in the 16th century.
