计算lim﹛x²/[(1+5x)∧0.2-(1+x)]﹜x趋向于0 计算极限 lim(1-x)^1/x x趋向0 lim(1+e^1/x)^x,x趋向于+0 lim((1+x)^5-(1+5x))/(x^2+x^5) x趋向于0 求lim x趋向于0(arctanx)/(x^2+1) lim(1-2^x)^sinx x趋向于－0 lim（x趋向于0）（1-cosx)/x^2 lim(x趋向于0)sinx/x=1,那么lim(x趋向于0)x/sinx=?怎么算? lim(x趋向于无穷)(1+3/x)^(x-3) 计算极限n趋向于0,lim(x+e^2x)^(1/sinx) lim(1-x^2-e^-x²)/(sinx^4) x趋向于0 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
