lim (x-1)^3 -1

lim（x-3/x+1）^x lim趋向无穷大 极限函数计算lim( x^3 / sinx - x )lim( (1/e^x-1)-(1/x) ) lim(x->0)((2-x)/(3-x))^1/x lim(x趋向于无穷)(1+3/x)^(x-3) 都是x趋向与0的1.lim {ln[1+x+f(x)/x]}/x=3 为什么可以推出 lim f(x)/x=02.lim lim(x趋向无穷)[1-(2/x)]^3x lim(x->2) {(3x+16)^1/2-4}/x 极限lim(x^2+2x+3)/(x-1) 求极限lim(1-2/x+3/x^2)^x 求lim(x→0)x cos 1/x lim(x→∞)x^2/ (3x-1)的极限 lim(1-sinx)^1/x lim(0-∞)/(x+1)
