微积分.导数 lim x->1 { (ln x - x +1) / (x - 1) ^2 } 求值!
lim(x->0)(ln(1+x))/x 不用导数
【急】大一微积分lim[x-x^2ln(1+1/x)] x趋近于无穷
ln(x/1-x)导数
微积分题目求助求助谢谢了ln(1+3^x)/ln(1+2^x) lim趋向正无穷
lim(x->0)ln(1+2x)/e^x-1
lim(x→0)ln(1-2x)/x
lim(x趋向0)ln(1+sin x)/x^2
lim(x趋于0)[ln(1+2x)]/x
求教大虾lim x->∞ 2x^2+x/x^2-2x+1 求f(x)=ln sinx,在x=π/6的导数值.
lim((ln(1+x))/x)^(1/x) x->无穷大
lim(x趋近于0)[1/ln(x+根号1+x^2)-1/ln(1+x)]
1、lim ln(1+x+2x^2)+ln(1-x+x^2)/secx-cosx
