lim(x→1）(x-x^x)/(1-x+Inx)的极限?
举一反三
- 【单选题】若 f ( x ) = ( x − 1 ) x 2 − 1 2 , g ( x ) = x − 1 x + 1 ,则? A. f ( x ) = g ( x ) "> f ( x ) = g ( x ) B. lim x → 1 f ( x ) = g ( x ) "> lim x → 1 f ( x ) = g ( x ) C. lim x → 1 f ( x ) = lim x → 1 g ( x ) "> lim x → 1 f ( x ) = lim x → 1 g ( x ) D. 以上等式均不成立
- 计算极限lim(x趋向于无穷大){[(a^x)+1]/x}^1/x,(a＞0,a不等于1)
- lim,x区于1,x^2-3x+2/x^2-1计算极限
- 求极限lim(x→1)(2/x^2-1)-(1/x-1)
- ①lim(x→∞)sin(1/x)/(1/x)等于多少?②lim(x→0)sin(1/x)/(1/x)等于多少?
