求lim x趋向于0(x-sinx)/tanx^3

求lim x趋向于0(x-sinx)/tanx^3 求极限(x趋向于0时）lim[sinx-sin(sinx)]/(sinx)^3 lim (x趋向于0)sin(sinx)/sinx lim(x趋向于0)((tanx-sinx)/(x*(sinx)^2)) 求极限, 求极限：lim(x趋向于0)(sinx-tanx)/x=?它和lim(sinx+tanx)/x有区别吗? lim(sinx)^tanx (x趋向于pai/2)求极限 lim ln(sinx/x)的极限.x趋向于0 lim(x趋向于0)e^sinx/x lim(x趋向于0)(tanx-sinx)/x^3=? lim x趋向于0 （tanx-sinx)/x lim (x趋向于0) sin(sinx)/x lim(x趋向于0)sinx/x=1,那么lim(x趋向于0)x/sinx=?怎么算? 不用洛必达法则求lim(x趋向于0) (sinx-x)/x^3的极限 lim x-sinx/x(e^2-1)求极限x趋向于0 求极限,当x趋向于0,lim(x-tanx)/(x^2*sinx), 求极限 lim (x趋向于0) x^3/(x-sinX) lim(sinx/x)^(1/x^2)x趋向于0用洛必达法则求极限, x 趋向于0 求lim(cos1/x+2/sinx-1/ln(1+x))
