(1)f‘(x^2)=1/x,x>0,求f(x)(2)g''(x^2)=x^3,x>0,求g(x)(1)f‘(x^2)=1/x,x>0,求f(x)(2)g''(x^2)=x^3,x>0,求g(x)(1)f

(1)f ‘ (x^2)=1/x,x>0,求f(x)(2)g ' (x^2)=x^3,x>0,求g(x)
(1)f ‘ (x^2)=1/x,x>0,求f(x)
(2)g ' (x^2)=x^3,x>0,求g(x)

(1)f ‘ (x^2)=1/x,x>0,求f(x)(2)g ' (x^2)=x^3,x>0,求g(x)
就是换元,f'(x^2)=1/x,f'(x)=1/√x,f(x)=2√x
g'(x^2)=x^3,g'(x)=x^(3/2),g(x)=(2/5)*x^(5/2)
