求极限lim x->0 ln(1+sin3x)/arcsin(x+x^2)

求极限lim x->0 ln(1+sin3x)/arcsin(x+x^2) 用咯必达法则求极限（1）、lim(x→0）ln（1+x）/x；；2、lim(x→∏)sin3x/tan5x lim x趋于0 ln (1+2x)/sin3x 用洛必达法则求极限：lim（x→0)(ln sin3x)/(ln sinx) 求下列极限 lim{n[ln(n+2)-lnn]}趋向于无穷 lim ln(1+2x)/sin3x趋向于0 极限Lim(x->0)(sin3x)/x= 求极限习题做法1.lim e^(sin3x) - 1x->0 ------------------- = In(1+2x 求极限 lim x趋近于0 sin3x／7x 求lim(x→0)x/sin3x的极限 求极限lim(x→0)sin3x/x 求极限lim Ln(1+x) /x > .< x→0 lim(x-0)arcsin(2x-1)求函数的极限
