lim(1-2x)∧1/x x趋向于正无穷

lim(1-2x)∧1/x x趋向于正无穷 求极限lim[x-x^2ln(1+1/x)] 其中x趋向于正无穷大 lim(x趋向于正无穷) (根号x^2+x -根号x^2+1) 求极限lim(根号x^2-x+1减去x),x趋向于正无穷大 lim x趋向于正无穷x(√1+x^2 -x )= lim(x趋向于正无穷大时)(1-1/X)^(x^1/2) lim(1+2/X)的3X方,同时X趋向于正无穷 lim(1-2x)^1/x x趋向于0 lim(x趋向于0)(x*cotx-1)/(x^2) lim(1+3x)^(2/x)x趋向于零 lim(x趋向于正无穷)(1+x)^1/x乘以(1+1/x)^x 求lim(1+1/x) (2-x^2)趋向于无限时的极限 lim ln(1+x)/x x趋向于－1正答案是正无穷 为什么? 当x趋向于正无穷,求lim{{(x+1）^2*(3x-1)^3}/x^4*(x+4)} lim(x趋向于正无穷大时）[√(x^2+2x)-√(x-1)]/x lim x趋向于正无穷 (x-1/x+1)的x幂求解 x趋向于正无穷 lim(ln(1+x)/x)^(1/x)= 求极限lim(e^3x-5x)^1/x x趋向于正无穷
