f(x)=2SIN^2(x+π\4)-cos(2x+π\6) 化简 谢 函数f(x)=-√2(sin2x+π/4)+6 sin x cos x-2cos²x+1 化简f(x)=(1+√2*cos(2x-π/4))/sin(π/2-x) 已知函数f(x)=cos^2(x-π/6)-sin^2x化简 已知函数f(x)=cos(2x-π/3)+sin^2 x-cos^2 x 已知函数f(x)=cos(2x-π\3)+sin²x-cos²x 已知f(x)=cos^2x+sinxcosx g(x)=2sin(x+π/4)sin(x-π/4) 已知f(x)=cos^2x/1+sin^2x求f'(π/4) 已知函数f(x)=cos(2x-π/3）+2sin(x-π/4）sin(x+π/4)=sin(2x-π/6) , 证明∫( 0,π／2 ) (f sin x/(f sin x+f cos x) dx=π /4 已知函数f(x)=[6cos(π+x)+5sin^(π-x)-4]/cos(2π-x),且f(m)=2,求f(-m)的值 已知f(x)=-1/2+sin(π/6-2x)+cos(2x-π/3）+cos平方x.
