f(x)=(x+1)(2x+1)(3x+1).(nx+1),求f''(0)f(x)=(x+1)(2x+1)(3x+1)....(nx+1),求f''(0)万分感谢f(x)=(x+1)(2x+1)(3x+1
f(x)=(x+1)(2x+1)(3x+1).(nx+1),求f'(0)f(x)=(x+1)(2x+1)(3x+1)....(nx+1),求f'(0)万分感谢
f(x)=(x+1)(2x+1)(3x+1).(nx+1),求f'(0)
f(x)=(x+1)(2x+1)(3x+1)....(nx+1),求f'(0)万分感谢
f(x)=(x+1)(2x+1)(3x+1).(nx+1),求f'(0)f(x)=(x+1)(2x+1)(3x+1)....(nx+1),求f'(0)万分感谢
f(x)=y=(x+1)(2x+1)(3x+1).(nx+1),求f'(0)
两边取自然对数得:lny=ln(x+1)+ln(2x+1)+ln(3x+1)+.+ln(nx+1)
两边对x取导数得y'/y=1/(x+1)+2/(2x+1)+3/(3x+1)+.+n/(nx+1)
故f'(x)=f(x)[1/(x+1)+2/(2x+1)+3/(3x+1)+.+n/(nx+1)]
∴f'(0)=f(0)(1+2+3+.+n)=f(0)(1+n)n/2
因为f(0)=1,故f'(0)=n(n+1)/2.
