limx→0 (sinx/x)∧(1/x∧3)
limx→0 (sinx/x)∧(1/x∧3)
limx→0 (sinx/x)∧(1/x∧3)
=limx→0 e∧ln(sinx/x)^(1/x^2)
=e∧limx→0 (lnsinx-lnx)/x^2(这是0/0型,运用洛必达法则)
=e∧limx→0 (cosx/sinx-1/x)/2x
=e∧limx→0(xcosx-sinx)/(2x^2sinx)
=e∧limx→0(cosx-xsinx-cosx)/(4xsinx+2x^2cosx)
=e∧limx→0-xsinx/(4xsinx+2x^2cosx)
=e∧limx→0-sinx/(4sinx+2xcosx)
=e∧limx→0-cosx/(4cosx+2cosx-2xsinx)
=e∧-1/6
limx→0 (sinx/x)∧(1/x∧3)
limx→0 (e^x-1)x^2/x-sinx
limx→1 x^2-x+1/x-1= limx→0+x^sinx=
limx→0[sinx-sin(sinx)]sinx/x^4
limx→0+(x^sinx)求极限
limx→0 (tanx-sinx)/x
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 e^sinx(x-sinx)/(x-tanx)
limx→0 5x-sinx/3x+7sinx
limx→ 0(2x-sinx)/(x+sinx)
limx->0(x-sinx)/(x+sinx)
limx→0(1/sinx-1/x)求极限
求limx→0 (e^x-1)sinx/1-cosx
limx→0(1+3x)^(1/sinx) 求解答.
limx→0,sinx /x=1 为什么
