f(x)=(1+cos 2x)*sin^2 x
求导f(x) = cos(3x) * cos(2x) + sin(3x) * sin(2x).
已知f(x)=sin(x/2) + cos(x/2) +[cos(x/2)]^2-1/2
化简f(x)=2cos(x/2)·(sin(x/2)+cos(x/2))-1
已知函数f(x)=2Cos x(Sin x-Cos x)+1
f(x)为奇函数,x>0,f(x)=sin 2x+cos x,则x
设f=[sin(2/x)]=1+cosx,求f(x),f[cos(2/x)].
f(x)=(1+cos2x)/[4sin(pai/2+x)]-asin(x/2)cos(pai-x/
已知函数f(x)=1/2(sin x+cos x)-1/2|sin x-cos x|,求f(x)值域
已知f(x)=cos^2x/1+sin^2x求f'(π/4)
f(x)=cos(2x-派/3)-2sin x*cos (派/2+x)
已知f(x)=cos(x/2)[sin(x/2)-cos(x/2)],其导为?
已知函数f(x)=cos(2x-π/3)+sin^2 x-cos^2 x
