hyperbola
Significado: A symmetrical open curve with two branches, formed by the intersection of a cone with a plane at an angle steeper than its side.
A hyperbola is one of the four conic sections and consists of two separate, mirror-image curves called branches. It is defined by the equation x²/a² - y²/b² = 1. Hyperbolas appear in physics to describe phenomena such as the paths of certain comets and the shape of cooling towers. Not to be confused with hyperbole, the rhetorical device.
Ejemplos
- The orbit of the comet traced a hyperbola as it passed through the solar system. 彗星在穿越太阳系时,其轨道呈双曲线形状。La órbita del cometa trazó una hipérbola al atravesar el sistema solar.彗星の軌道は太陽系を通過する際に双曲線を描いた。혜성의 궤도는 태양계를 통과하면서 쌍곡선을 그렸습니다.
- The maths lecturer demonstrated how to derive the asymptotes of a hyperbola. 数学讲师演示了如何求双曲线的渐近线。El profesor de matemáticas demostró cómo derivar las asíntotas de una hipérbola.数学の講師は双曲線の漸近線の導出方法を実演した。수학 강사는 쌍곡선의 점근선을 유도하는 방법을 시연했습니다.
- Navigation systems once used hyperbola-based calculations to determine a ship's position. 航海系统曾经使用基于双曲线的计算来确定船舶位置。Los sistemas de navegación utilizaban en su día cálculos basados en hipérbolas para determinar la posición de un barco.かつて航海システムは双曲線に基づく計算を用いて船の位置を特定していた。과거의 항법 시스템은 쌍곡선에 기반한 계산을 이용하여 선박의 위치를 결정했습니다.
