A hyperbola is a conic section defined by two symmetrical branches separated by a transverse axis, with its shape determined by the distance between its foci. The standard equation of a hyperbola is (x/a)^2 - (y/b)^2 = 1, and its components include foci, vertices, and asymptotes, which are crucial for understanding its properties and applications. Hyperbolas can also be expressed using trigonometric functions and polar coordinates, making them relevant in various scientific fields.
