F(x)=f(cos~2x)+f(sin~2x)的导数 急————————

f'(sin^2x)=cos^2x,求f(x)f'((sin^x)^2)=(cos^x)^2 f'(sin x)=1-cos x 求f''(x) f'(cos^2x)=sin^2x ,f(0)=0,求f(x) f(x)=cos(2x)+2sin(x)化简 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) 设f(sin x/2 )-1+cos x ,求f(x)、f(cos x/2 ). f(cos x)=2-sin 2x,则f(sin x)=? f(sin x)=cos2X 那么f(cos x)= 若f(cos x)=cos 2x,则f(sin 15度）的值? f(x)=sin(x+π/4)图像怎样变成F(x)=cos(2x) f(x)=cos(2x+60)+sin^2x 求f(x)的值域 证明∫( 0,π／2 ) (f sin x/(f sin x+f cos x) dx=π /4 已知f(x)=sinx+cosx,f'(x)=3f(x),f'(x)为f(x)的导数,则(sin^2x-3)/(cos^2+1)=?
