asymptote
意味: A line that a curve approaches ever more closely but never actually reaches, no matter how far the curve is extended.
Asymptotes can be horizontal, vertical, or oblique, and they describe the limiting behaviour of a function. For instance, the function y = 1/x has asymptotes along both the x-axis and y-axis. The concept is used metaphorically to describe something that is approached but never quite attained, as in 'asymptotic improvement.' It is a highly specialised term, largely confined to mathematics and the sciences.
例文
- The graph of the function approaches the asymptote but never crosses it. 该函数的图形不断趋近渐近线,但永远不会与之相交。La gráfica de la función se acerca a la asíntota pero nunca la cruza.この関数のグラフは漸近線に近づきますが、決して交わりません。이 함수의 그래프는 점근선에 가까워지지만 결코 교차하지 않습니다.
- As x tends to infinity, the curve draws ever closer to its horizontal asymptote at y = 0. 当x趋向无穷大时,曲线越来越接近y = 0处的水平渐近线。A medida que x tiende a infinito, la curva se aproxima cada vez más a su asíntota horizontal en y = 0.xが無限大に近づくにつれ、曲線はy = 0の水平漸近線にますます近づきます。x가 무한대로 갈수록 곡선은 y = 0의 수평 점근선에 점점 더 가까워집니다.
- The lecturer used the concept of an asymptote to illustrate limits in the introductory calculus module. 讲师用渐近线的概念来说明微积分入门课中的极限。El profesor utilizó el concepto de asíntota para ilustrar los límites en el módulo introductorio de cálculo.講師は微積分の入門講座で極限を説明するために漸近線の概念を用いました。강사는 미적분 입문 과정에서 극한을 설명하기 위해 점근선의 개념을 사용했습니다.
