lim(x→0)=（arctanx-x）/ln(1+2x^3)

lim(x→0)=（arctanx-x）/ln(1+2x^3) lim（下面是x→100 ）arctanx= lim(x趋近于0+）arctanx=? lim(x+arctanx)/(x-arctanx) (x→∞) 求lim(x→0)arctanx/x的极限, 求极限解题lim(x→∞)=arctanx/x 一.x---->0时,证明lim(arctanx)/x=1 lim(x趋向0)（x-arctanx）/（x-arcsinx）=? 求极限lim(x→0)sinxsin(1/x);lim(x→∞)(arctanx/x) 当x趋向于0+,lim arctanx/lnx=? lim(n趋近于0)(arctanx)/x lim(arctanx/sinx) x－>0 lim(x→0 )(arctanx/x)^(1/x^2)求极限求lim(x→0 )(arctanx/x)^(1/x^2) lim(x+sinx)/(3x-arctanx)(x趋于无穷） 证明:arctanx和x是等价无穷小量证明:lim(x→0)arctanx/x=1,即证明arctanx和x是等价无穷小量,用洛必达法则作可以吧?这题好像是0/0求极限的类型 lim(x→∞)arctanx/x的极限 lim(x→+∞)(2/π*arctanx)^x求极限 求极限lim(2/π*arctanx)^x x→∞
