sin(2x+pai)=?sin(2x+0.5pai)=?
sin(2x+pai)=?sin(2x+0.5pai)=?
sin(2x+pai)=?sin(2x+0.5pai)=?
sin(2x+pai)=sin2xcosπ+cos2xsinπ=-sin2x
sin(2x+0.5π)=sin2xcos0.5π+cos2xsin0.5π=cos2x
sin(2x + π) = -sin(2x)
sin(2x + 0.5π) = cos(2x)
sin(2x+pai)=sin2xcosπ+cos2xsinπ=-sin2x
sin(2x+0.5π)=sin2xcos0.5π+cos2xsin0.5π=cos2x
x属于(pai/4,pai),sin(x+pai/4)=√2/3,sin(x-pai/4)=
化简!f(x)=sin(pai-x)cos(3/2pai+x)+sin(pai+x)sin(3/2pai-x)求单调减区间。
f x =sin(pai*x/4-pai/6)-2(cos pai*x/8)^2+1
sin(2x+pai)=?sin(2x+0.5pai)=?
sin(2x+pai)=?sin(2x+0.5pai)=?
y=sin(x-pai/6)怎么变成y=2sin(X/2-pai/6)
sin^2(pai/3-x)+sin^2(pai/6+x)=如题
已知sin(3pai-x)=-2sin(pai/2+x),则sinxcosx等于
sin(x+pai/6)+sin(x-pai/6)=什么
sin(x+pai/6)+sin(x-pai/6)=
若函数f(x)=sin(2x+θ) (-pai
sin(x+pai/6)=1/4,sin(5/6pai-x)+sin^2(11/6pai-x)的值为
sin(pai/4+x)sin(pai/4-x)=1/6,x在(pai/2,pai) 求sin4x要详细过成,我没有分了,
函数f(x)=sin(pai/2+x)cos(pai/6-x)的最大值
已知k=[2(sin x)^2+sin 2x]/(1+tan x),pai/4
函数Y=SIN(2X+PAI /3)+SIN(2X-PAI /3)取得最小值是的X应去值是?
函数f(x)=sin^2(x+pai/4)-sin(x-pai/4)的周期和奇偶性
解sinx=2sin(pai/3-x)
