y=sin(x+π/3)sin(x+π/2)
=(sinxcosπ/3+cosxsinπ/3)cosx
=1/2sinxcosx+√3/2 cos²x
=1/4sin2x+√3/4(cos2x+1)
=1/4sin2x+√3/4 cos2x+√3/4
=1/2(1/2sin2x+√3/42cos2x)+√3/4
=1/2sin(2x+π/3) +√3/4

函数y=sin（x+π3 化简y=sin^2(x)+2sin(x)cos(x)+3cos^2(x) y=sin2x y=sin(x+π/3) y=3sin(2x+π/3) 三角函数 y+1=sin(2x-0.5π)化简已知函数y=-2sin(3x+π/3) 函数y=3sin（2x-π3 求函数y=2sin（2x+π3 已知函数y=2sin(2x+π/3) 求导数 y=sin^2(2x+π/3) 函数y=2sin(2x+π3) y=2sin(1\2x-π\3)+1 判断y=sin(2x+3π/2)奇偶性
