sin(sin(sin(sin(x)=cos(cos(cos(cos(x),X等于多少?
cos x/sin x+sin x/(1+cos x) 化简.
(1+cos x-sin x)/(1-sin x-cos x)+(1-cos x-sin x)/(1-sin x+cos x)=?
cos x /sin x=
怎么证明2(1-sin x)(1+cos x)=(1-sin x+cos x)^2
y=(sin(x)-1)/(cos(x)+(cos(x))/(sin(x)+1)的奇偶性
为什么cos(sin(tan x)))=1
求证(cos^2 x-sin^2 x)(cos^4 x+sin^4 x)+1/4 sin 2x sin 4x=cos 2x
已知(1+sin x)/cos x=-1/2,则cos/(sin x-1)=?
y=2cos x (sin x+cos x)
2cos x (sin x -cos x)+1
Sin x-sin y=2/3 cos x-cos y=1/2 求cos(x-y)
求证:tan x/2=sin x/(1+cos x)
求证:1-sin(x)=cos(x)*tan(x/2)
f'(sin x)=1-cos x 求f''(x)
证明:(1 + tan x) / (sin x + cos x) = 1 / cos x
cos(x)=1 +sin(x)cos(x)用两种方法求x
化简(sin x+cos x-1)(sin x-cos x+1)/sin 2x
