sin(x+pai/6)+sin(x-pai/6)=sin(x+pai/6)+sin(x-pai/6)=sin(x+pai/6)+sin(x-pai/6)=sin(x+π/6)+sin(x-π/6)=
sin(x+pai/6)+sin(x-pai/6)=
sin(x+pai/6)+sin(x-pai/6)=
sin(x+pai/6)+sin(x-pai/6)=
sin(x+π/6)+sin(x-π/6)
=sinxcos(π/6)+cosxsin(π/6)+sinxcos(π/6)-cosxsin(π/6)
=2sinxcos(π/6)
=2sinx(√3/2)
=√3sinx
sin(x+pai/6)+sin(x-pai/6)=什么
sin(x+pai/6)+sin(x-pai/6)=
化简sin(pai-x)
f x =sin(pai*x/4-pai/6)-2(cos pai*x/8)^2+1
y=sin(x-pai/6)怎么变成y=2sin(X/2-pai/6)
化简:根号3 sin(2x+pai/3)+ 2sin^2(x+pai/6)
sin^2(pai/3-x)+sin^2(pai/6+x)=如题
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
x属于(pai/4,pai),sin(x+pai/4)=√2/3,sin(x-pai/4)=
sin(x+pai/6)=1/4,sinx=?
sin(pai/3-x)等于sinx?
y=sin(5pai/6-x/2)cos(pai/6+x/2)单调减区间
求函数y=sin(pai/2+x)*cos(pai/6-x)的最大值和最小值
函数y=2sin(pai/6-2x)(x∈0,pai)
若sin(pai/6-x)=1/3,则cos(2pai/3+2x)=?
函数y=sin(2x+pai/6)+cos(2x+pai/3)的最大值?
