渐近线是双曲线中具有特殊性质的元素,它在解决双曲线的诸多问题中都有着重要的且不可替代的功能.请看:1.功能之一:控制曲线范围和发展趋势双曲线只能位于由它的两条渐近线所构成的且含实轴的一对对顶角之内,这就从宏观上控制了双曲线的范围;同时双曲线如(x~2)/(a~2)-(y~2)/(b~2) Asymptotes are special elements in hyperbolic curves that have important and irreplaceable functions in solving hyperbolic problems. See: 1. One of the functions: The range and trend of the control curve Hyperbolic Can be located within a pair of apex angles formed by its two asymptotic lines and containing a real axis, which macroscopically controls the hyperbola range; at the same time hyperbola such as (x ~ 2) / (a ~ 2) - (y ~ 2) / (b ~ 2)
