lim趋现于0,x(x+3)/sinx

lim趋现于0,x(x+3)/sinx limx趋现于0,x(x-3)/sinx lim(x-sinx)/(x+sinx),x趋近于0 lim(x-sinx)/(x+sinx),x趋近于0 lim(sinx+e^x)^(1/x) x趋近于0 lim（x/sinx）x(趋近于0)为什么等于lim(cosx)x(趋近于0) lim sinx^x(x趋近于0+)求极限 求LIM(1-COSX)/X*SINX X趋近于0 x趋近于0时,lim(sinx+tanx)/x=? 求lim x^sinx x正趋近于0RT Lim(sinx/x)^1/(1-cosx) X趋近于0 x趋近于0时,lim(x-sin(3x))/(x+sinx) 求下面两个极限lim x[(x^2+1)^(1/2)-x] x趋近于+∞；lim (tanx-sinx)/x^3 x趋近于0； 当x趋近于0时,lim(tanx-sinx)=? lim(e^sin2x-e^sinx)/tanx,x趋近于0 lim(x-sinx/x+sinx) x趋近于1 lim趋近于0((3+2sinx)*x-3*x)/((tanx)*2)求极限 lim x趋近于0[(1+tanx)/(1+sinx)]^(1/x^3)
