Par\u00e0bola<\/a><\/p>\n

Una primera definici\u00f3 com a lloc geom\u00e8tric, requereix considerar un punt anomenat focus i una l\u00ednia recta que no passi per ell anomenada directriu. El conjunt de punts que s\u00f3n equidistants tant de la directriu com del focus forma la par\u00e0bola.
\nUna segona definici\u00f3 \u00e9s com a secci\u00f3 c\u00f2nica. La par\u00e0bola \u00e9s la intersecci\u00f3 entre una superf\u00edcie c\u00f2nica i un pla paral\u00b7lel a un altre pla tangent a la superf\u00edcie c\u00f2nica. La par\u00e0bola forma part de la fam\u00edlia de les c\u00f2niques, que s\u00f3n les corbes resultants de les diferents interseccions entre una superf\u00edcie c\u00f2nica i un pla segons la seva posici\u00f3 m\u00fatua.
\nUna tercera definici\u00f3 \u00e9s algebraica. Una par\u00e0bola \u00e9s el gr\u00e0fic d’una funci\u00f3 quadr\u00e0tica, per exemple y = ax\u00b2 .<\/p>\n
