Hipérbolas

Hipérbolas are a type of conic section, which is a curve formed by the intersection of a plane with a double cone. In the case of a hipérbola, the plane intersects the cone such that it is parallel to one of the cone's generating lines. This results in a curve that has two separate branches, each resembling a pair of curves opening in opposite directions.

The standard form of a hipérbola is given by the equation:

(x^2 / a^2) - (y^2 / b^2) = 1

where 'a' and 'b' are constants that determine the shape of the hipérbola. The distance between the two branches of the hipérbola is given by 2a, and the distance between the vertices on each branch is given by 2b.

Hipérbolas have several key properties:

1. **Asymptotes**: A hipérbola has two asymptotes, which are straight lines that the curve approaches but never touches. The equations of the asymptotes are given by y = ±(b/a)x.

2. **Foci**: Unlike ellipses, hipérbolas have foci that lie outside the curve. The distance between the foci is given by 2c, where c is determined by the relationship c^2 = a^2 + b^2.

3. **Eccentricity**: The eccentricity of a hipérbola is a measure of how much the hipérbola deviates from being circular. For a hipérbola, the eccentricity is always greater than 1.

Hipérbolas have various applications in mathematics, physics, and engineering. In physics, they are used to describe the trajectory of objects under the influence of a central force, such as a planet orbiting a star. In engineering, they are used in the design of optical systems and in the analysis of wave propagation.
