x趋于1时，lim sin πx与πx为什么不是等价无穷小？ - 知乎
2020年1月16日 · 首先x趋于1时，sin (pix)趋于0，而pix趋于pi。 等价无穷小 就是两个都应该趋于0，二者的比值 极限 为1，才是等价无穷小。 sin (pix)=-sin (pi (x-1))，x趋于1时sin (pix)的等价无穷小是- (pi (x-1))，等价无穷小带入sin (pix)/pi也能证明极限是0。 这个等价无穷小明显是在x-0时成立的。 当x-1，时sinπx-0，而πx-π。 这能是 等价无穷小 吗？ 分子趋于0，分母是常数，极限就是0。 因为 pix 不是无穷小. 它求出来的极限不也是0吗，为什么不能用sinx~x替换？

How do you evaluate #lim_(x->1)# #(sin(7pix))/(sin(8pix))
2017年2月21日 · Let's use l"Hospital's Rule. lim_ (x->1) (sin (7pix))/ (sin (8pix)) = lim_ (x->1) (7pi cos (7pix))/ (8 pi cos (8pix)) = (7 pi cos (7pi))/ (8 pi cos (8pi)) = (7 (-1))/ (8 (1)) = -7/8.
