f(x)= (x^2)sin(1/x),x≠00 ,x=0x0=0求函数在给定点处的导数f'(x0)

f(sin 2/x )=1+cosx 求f(x) f(x)={(1-e^x)/sin(x/2) ,x>0 ;ae^2x,x 傅里叶级数作图f（x）=2sin[x] - sin[2x] + 2/3sin[3x] - 1/2sin[4x]我用mathematica输入程序Plot[{2sin[x],-2sin[x],2sin[x] - sin[2x],-2sin[x] + sin[2x],2sin[x] - sin[2x] + 2/3sin[3x],-2sin[x] + sin[2x] - 2/3sin[3x],2sin[x] - sin[2x] + 2/3si f'(sin x)=1-cos x 求f''(x) f(x)=sin-1次方 x ,求f'(x) f(sin^2x)=x/sinx 求f(x) 已知函数f(x)=(1+1 anx)sin^2x+m sin(x+π/4)sin(x-π/4) f(x)=（1+cotx)sin^2x-2sin(x+π/4)sin(x-π/4)还有一题, f(x)=(1+1/tanx)sin(x)^2化简 f(x)=sin^2x+sinxcosx-1/2,化简 复合函数f（x）=x^2sin(1/x) （x>0） f(x)=0 x 化简f(x)=(1+cos2x)sin^2x f(x)=sin(πx^2)(-1 f(x)为奇函数,x>0,f(x)=sin 2x+cos x,则x 已知函数f(x)=-1/2+sin(5/2x)/2sin(x/2)(0 设F(x)>0,F(0)=1,F‘(x)=f(x),且f(x)F(x)=sin^2(2x)(x>=0),求f(x).是F'（x)=f(x) f(x)=cos(2x)+2sin(x)化简 求导f(x) = 4x^3 + sin(x^2)
