f(x)=3^x+x^3+x^(x)sinx 求f'(x)

f(x)=x^3-6sinx 求f`(x) f(x)=3^x+x^3+x^(x)sinx 求f'(x) 已知f(x)=3^x sinx+ln x,求f'(x), F(X)满足F(x)+2f(x分之1)=3X,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x)? 已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x) 已知f(3sinx)=cos方x/sin方x,求f(x)= f(x)=sin[(sinx)^2],g(x)=3x^2+4x^3,求当x趋近于0时,f(x)/g(x)的极限 已知f (x)+2f(-x)=x^3+x^2,求f(x) (1) f(x)=X²+3x 求（X+1）与f[f(x)] 已知f(x+1)+2f(-x)=3x²+x,求f(x)
