limx-0时sinx^2/x(x+1)应该=1还是0

limx—＞0(sinx/x)^[1/(sinx)^2] limx→0 (e^x-1)x^2/x-sinx limx→1 x^2-x+1/x-1= limx→0+x^sinx= limx趋近于0(sinx/x)^(1/x^2) limx趋于0 [ (1/x)-(1/sinx)] limx->0(sinx/x)^(1/(1-cosx)) limx趋于0 1/x sinx= limx-0(sinx/x)为什么等于1 limx→ 0(2x-sinx)/(x+sinx) limx->0(x-sinx)/(x+sinx) 求limx->0 (1+3x)^(2/sinx) limx-0 (sinx-tanx)/2x(1-cosx) limx趋于0,ln(1-2x)/sinx,求极值 limx~0 sinx-x/（x-e^x+1）x limx-0时sinx^2/x(x+1)应该=1还是0 limx趋于0 sinx/x急limx趋于0 sinx/x=1 为什么! limx趋向于0时x-sinx/x+tanx limx趋于0 ((1+x)^(1/x)-e)/sinx 极限
