lim x->0 (sin x-tan x)/sin (x^3)
lim x->0 (sin x-tan x)/sin (x^3)
lim x->0 (sin x-tan x)/sin (x^3)
lim x->0 (sin x-tan x)/sin (x^3)
=lim x->0 tanx(cosx-1)/(x^3)
=lim x->0 x(-1/2x²)/(x^3)
=-1/2
罗比达法则, 分子分母同时求导
lim (x->0) [tan(tan x)-sin(sin x)]/(tan x -sin x)
lim x->0 (sin x-tan x)/sin (x^3)
Lim*(sin x/tan x)x->0
lim(sin(aX)/tan(bX))(X趋近于0)
求 lim(tan x-sin x)/(sin x)^3 x趋于0的极限值详细步骤
lim(x→0)[tan(2x+x^3)/sin(x-x^2)]
lim[(sin x)^tan x],x趋向于Pai/2
lim(x→0)(e^tan x-e^sin x)/x^3,rt
lim(x→0) [1-cos(x^2)]/sin(x^2)tan(x^2)]=?
lim(tan^3(3x)/(X^2sin(2x))(x趋近于0)
求 lim (sin x)^3/ (tan x-sin x) 当x趋于0的极限值好吧,我会了、、、
救助,一道高数文科题求下列极限1、lim(x->0)sin nx/tan mx ,n*m不为02、lim(x->0)x-sin x/x+ tan x3、lim(x->0)tanx-sinx/x^3
当x趋于0时:lim (tan x - sin x )/x^3 lim [(a^x+b^x+c^x)/3]^(1/x) ( a,b,c > 0 )
lim (x^x-sin(x)^x)/(sin(x)sin(x)ln(1+tan(x))) x趋于零
lim arc tan(x-sin(lnx)) n趋于无限大
高数,求极限的问题 lim [tan(tanx)-sin(sinx)] / (tanx高数,求极限的问题lim [tan(tanx)-sin(sinx)] / (tanx - sinx)x→0
当X趋于0时lim(tan x -sin x)/x∧3的极限 请用等价无穷小替换
1.lim x→0,(tanx-sinx)/(sin2x)^3 2.lim x→0,sin(x-1)tan(x-1)/2(x-1)lnx ..
