求极限lim(x→0)[tan3x/x]
求极限lim(x→0)[tan3x/x]

求极限lim(x→0)[tan3x/x]
lim(x→0)[tan3x/x]
=lim(x→0)3[tan3x/3x]
=3
lim(x→1) (x²-2x+1)/(x²-1)
=lim(x→1) (x-1)²/[(x+1)(x-1)]
=lim(x→1) (x-1)/(x+1)
=0

lim(x→0)[tan3x/x]=3 lim(3x→0)[tan3x/3x]=3 lim(x→0)[sin3x/3x]lim(x→0)[1/cos3x]=3
lim(x→1)(x^2-2x+1)/(x^2-1)=lim(x→1)(x-1)^2/(x+1)(x-1)=lim(x→1)(x-1)/(x+1)=0

lim(x→0)[tan3x/x]
=lim(x→0)[3x/x]
=3
(1)lim(x---->1)(x-1)/(x+1)
=0/2
=0

lim(x→0)tan3x/x的极限怎么求? 求极限lim(x→0)[tan3x/x] lim 2x/tan3x x→0 求极限 lim sin2x/tan3x 求极限?(x→0) x→0 lim sin3x/tan3x 求极限 lim( tan3x-sin5x)/X X趋于0 求极限 lim（x趋于π/2)（tanx/tan3x）求极限求极限lim(x->0)(x^2+tanx-sin5x)/(tan3x-x^3) 求极限:tan3x/xlimX不为0 tan3x/x x→0+时求lim ln(tan3x)/ln(tan2x) 高数求极限一题 lim (ln tan3x)/(ln tan 4x) (x->0+) 极限lim（ x→π/2） xtanx / tan3x lim（ x→0）sin2x / tan3x sin2x lim ------- x→0 tan3x lim x趋近于0(tan3x/sin5x) 求极限?我有结果. limx→0tan3x/x计算极限 limx→0=(tan3x)/x 极限用洛必达法则求lim(x→π/2)tan3x/tanx
