lim(x趋向于无穷)(1+3/x)^(x-3)

lim(x趋向于无穷)(1+3/x)^(x-3) lim(arctan1/x)/(1/x),x趋向于无穷,为什么? x趋向于无穷时 lim (3x-1)/(x^3 乘以 sin(1/x^2 )) 求lim x趋向于无穷时(-X)/(2X^2+3x-1)答案 求极限lim(e^3x-5x)^1/x x趋向于正无穷 lim(1+2/X)的3X方,同时X趋向于正无穷 lim(x趋向无穷)[1-(2/x)]^3x lim趋向正无穷(x+1/x)^3x lim趋向正无穷(x+1/x)^3x 判断极限是否存在lim [n+(-1)^n]/n n趋向于无穷 lim |x|/x x趋向于0 lim x->趋向于无穷 根号X乘于（根号X+1-根号X-1） lim x趋向于无穷 (2^n+1+3^n+1)/(2^n+3^n)= 求lim x趋向于负无穷 (x/x+1)arctanx“X/(x+1)部分趋向于1” 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)(1+x)^1/x乘以(1+1/x)^x lim （x 趋向于无穷)e^-x^2*cosx lim x趋向于无穷 （arctanx）/x lim(xsinx)/x^2-4,x趋向于无穷
