Parabola
Videos
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 def

A bouncing ball captured with a stroboscopic flash at 25 images per second. The ball becomes significantly non-spherical after each bounce, especially after the first. That, along with spin and air resistance, causes the curve swept out to deviate slightly from the expected perfect parabola.

The supporting cables of suspension bridges follow a curve that is intermediate between a parabola and a catenary.
Quadratic equation

In mathematics, a quadratic equation is an equation that can be rearranged in standard form as a x 2 + b x + c = 0, where the variable x represents an unknown number, and a, b, and c represent kno
