lim x->0 (sin x-tan x)/sin (x^3)
lim (x->0) [tan(tan x)-sin(sin x)]/(tan x -sin x)
1/cos(x) - tan(x) = 3 求sin(x)1/cos(x) - tan(x) = 3求sin(x)
求 lim(tan x-sin x)/(sin x)^3 x趋于0的极限值详细步骤
(1+tan(x))/sin(2x)不定积分
lim(x→0)[tan(2x+x^3)/sin(x-x^2)]
[sin(540-x)/tan(900-x)]*[1/tan(450-x)*tan(810-x)]*[cos(360-x)/sin(-x)]
化简:sin(2派-x)tan(派+x)cot(-x-派)/tan(3派-x)cos(派-x)
已知tan=2,求(cos x+sin x)/(cos x-sin x)+sin^2x
求证tan^x-sin^2x=tan^2x*sin^2x
tan(x)-sin(x)等价无穷小tan(x)-sin(x)的等价无穷小
证明:(tan^2)x-(sin^2)x=(tan^2)x(sin^2)x
求证(3-sin^4 x-cos^4 x)/2cos^2 x=1+tan^2 x+sin^2 x
lim(tan^3(3x)/(X^2sin(2x))(x趋近于0)
lim [(1+tan x)/(1+sin x)]^(1/x^3) x趋于零
lim(x→0)(e^tan x-e^sin x)/x^3,rt
当x趋向于0时,(sin(x)-tan(x))/x^3 的极限怎么求?
