Mathematical problem pit
Dcac in mathematics, hyperbola (Greek)? περβολ? ",which literally means" beyond "or" beyond ") is a conic curve defined as two halves of a right-angled cone where planes intersect. It can also be defined as the trajectory of a point whose distance difference from two fixed points (called focus) is constant. This fixed distance difference is twice that of A, where A is the distance from the center of hyperbola to the vertex of the nearest branch of hyperbola. A is also called the semi-real axis of hyperbola. The focal points are located on the through axis, and their midpoint is called the center.
