将f(x)=2sin^4 x+2cos^4 x+cos^2 x-3化简化成y=Asin(wx+b)+c形式

已知函数f(x)=根号3sin2x+2sin(派/4+x)cos(派/4+x)将f(x)化为y=sin 将f(x)=cos(x/4+π/3)sin(x/4-π/2)化成标准三角函数 f(x)=(6sin^4x-7sin^2x+2)/(sin^2x-cos^2x) f(x)=sin(x+π/4)图像怎样变成F(x)=cos(2x) f(x)=cos(2x)+2sin(x)化简 f'(sin^2x)=cos^2x,求f(x)f'((sin^x)^2)=(cos^x)^2 将f(x)=2sin^4 x+2cos^4 x+cos^2 x-3化简化成y=Asin(wx+b)+c形式 将F (x) = 2 sin(2x) + 2√3 cos(2x)改写成 F (x) = A sin(2x+ B)的形式～ 证明∫( 0,π／2 ) (f sin x/(f sin x+f cos x) dx=π /4 将函数f(x)=cos(2x+pai/4)的图像向（ ）平移（ ）个单位长度,得到f(x)=sin(2x+pai/4) 已知f(x)=cos^2x/1+sin^2x求f'(π/4)求导 f(x)为奇函数,x>0,f(x)=sin 2x+cos x,则x f(sin x)=3-cos 2x,求f(cos x)=? 设f(sin x)=3-cos 2x,则f(cos x）=? 若F(sin x)=3-cos 2x 则F（cos x）=? f(sin x)=cos 2x +1 求 f(cos x) f(sin x)=3-cos 2x求f(cos x) f(cos x)=2-sin 2x,则f(sin x)=?
