已知函数F(x)=sinxCosx+Cos²x 求函数F(x)的最小正周期,并写出...

还有问题吗?

f(x)=sin²x+sinxcosx+cos2x =2分之(1-cos2x)+

Fx=cosx(1/2cosx-√3/2sinx)Fx=1/2co²x-√3/2s

(1)f(x)=32sin2x+1+cos2x2+a=sin(2x+π6)+a+12∴T=π由π2+

f(x)=cos^4x-2sinxcosx-sin^4x =(cos^2x+sin^2x)(cos

f(x)=sinxcosx+cos²x =(1/2)sin2x+(1+cos2x

希望有帮助!呵呵!

解: f(x)=sin²x+√3sinxcosx+2cos²x

有点乱码 1 f(x)=cos²x+sinxcosx =1/2(1+
