已知函数f(x)=2√3sin(x/2+π/4)cos(x/2+π/4)-sin(x+π)
f(x)=2√3sin(x/2+π/4)cos(x/2+π/4)-sin(x+π)
=√3sin(x+π/2)+sinx
这一步是怎么来的

已知函数f(x)=2√3sin(x/2+π/4)cos(x/2+π/4)-sin(x+π)f(x)=2√3sin(x/2+π/4)cos(x/2+π/4)-sin(x+π)=√3sin(x+π/2)+sinx这一步是怎么来的
x)=2√3sin(x/2+π/4)cos(x/2+π/4)-sin(x+π)
f(x)=根号3sin[2(x/2+π/4)]+sinx
f(x)=根号3sin(x+π/2)+sinx
