limx->0(sinx/x)^(1/(1-cosx))limx->0(sinx/x)^(1/(1-cosx))limx->0(sinx/x)^(1/(1-cosx))稍等,我给你贴图回答1)sinx
limx->0(sinx/x)^(1/(1-cosx))
limx->0(sinx/x)^(1/(1-cosx))
limx->0(sinx/x)^(1/(1-cosx))
稍等,我给你贴图回答
1)sinx x(x→0) 2)e^x-1 x(x→0) 3)(1+x)^a-1 ax(x→=lim[x/(x+x^2+3x^3)] sinx和x是等价无穷小 1-cosx和(1/2
先e后log
x->0,log(1+x)~x
e^(1/(1-cosx))*(sinx/x-1)=e^(sinx/x-1)/(1-cosx)
对指数洛必达
(cosx*x-sinx)/x^2*sinx=(-sinx*x+cosx-cosx)/3x^2=-x^2/3x^2=-1/3
(sinx/x)^(1/(1-cosx))=e^(-1/3)
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(sinx/x)^[1/(sinx)^2]
limx趋于0 sinx/x急limx趋于0 sinx/x=1 为什么!
limx->0(x-sinx)/(x+sinx)
limx~0 sinx-x/(x-e^x+1)x
limx→0 (e^x-1)x^2/x-sinx
limx→1 x^2-x+1/x-1= limx→0+x^sinx=
limx趋于0 ((1+x)^(1/x)-e)/sinx 极限
limx→0 (sinx/x)∧(1/x∧3)
limx趋近于0(sinx/x)^(1/x^2)
limx趋于0 1x(1/x—1/sinx)limx趋于0 1/x(1/x—1/sinx)
求极限,limx~0 (1-x)^(1/-sinx)
limx→0(1/sinx-1/x)求极限
limx趋向于0,(1/sinx-1/x)=?
求limx→0 (e^x-1)sinx/1-cosx
