<P> In mathematics , a parabola is a plane curve , which is mirror - symmetrical , and is approximately U-shaped when oriented as shown in the diagram below ( it remains a parabola if is differently oriented ) . It fits any of several superficially different mathematical descriptions , which can all be proved to define exactly the same curves . </P>
