已知函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)求f‘(2) 导数问题
f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)f'(x)=(x-1)'(x-2)(x-3)(x-4)(x-5)(x-6)+(x-1)(x-2)'(x-3)(x-4)(x-5)(x-6)+(x-1)(x-2)(x-3)'(x-4)(x-5)(x-6)+(x-1)(x-2)(x-3)(x-4)'(x-5)(x-...
若函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5),且f'(x)是函数f(x)的导函
做个变形,令f(x)=(x-1)*g(x),则f'(x)=g(x)+(x-1)*g'(x),则f'(1)=g(1)=1*2*3*4=12
f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5)的导数怎么求
解析如下:f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5)lnf(x)=lnx+ln(x-1)+ln(x-2)+ln(x-3)+ln(x-4)+ln(x-5)f'(x)\/f(x)=1\/x+1\/(x-1)+1\/(x-2)+1\/(x-3)+1\/(x-4)+1\/(x-5)∴f'(x)=f(x)[1\/x+1\/(x-1)+1\/(x-2)+1\/(x-3)+1\/(x-4)+1\/(x...
...f ( x )= x ( x -1)( x -2)( x -3)( x -4)( x -5),则 f ′(0)=...
-120 f ′( x )=( x -1)( x -2)( x -3)( x -4)( x -5)+ x [( x -1)( x -2)( x -3)( x -4)( x -5)]′,∴ f ′(0)=(-1)×(-2)×(-3)×(-4)×(-5)=-120.
函数f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5) 则f'(0)=?.请您说具体些
这个题很简单啊,先求f'(x)再求f'(0),f'(x)=(x-1)(x-2)(x-3)(x-4)(x-5)+x*(x-1)'(x-2)(x-3)(x-4)(x-5)+x(x-1)(x-2)'(x-3)(x-4)(x-5)+……所以f'(0)=(-1)*(-2)*(-3)*(-4)*(-5)=-120 ...
已知f(x)=(x-1)(x-2)(x-3)(x-4)(x-5),则f′(1)=__
∵f(x)=(x-1)(x-2)(x-3)(x-4)(x-5),∴令g(x)=(x-2)(x-3)(x-4)(x-5),则f(x)=(x-1)g(x)∴f′(x)=(x-1)′g(x)+(x-1)g′(x)=g(x)+(x-1)g′(x),则f′(1)=g(1)+(1-1)g′(1)=g(1)...
已知f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5),则f(0)=?
f(0)=0×﹙-1﹚×﹙-2﹚×﹙-3﹚×﹙-4﹚×﹙-5﹚=0
已知f(x)=(x-1)(x-2)(x-3)(x-4)(x-5),则f'(1)=?
答案是二十四 因为求的是一的导数值 所以把X减一看作一项 后边看作一项 利用乘法法则求导函数 求时现别化开你会发现后边的代一的话可以消掉 然后只给前边的带值就能求出
不用求函数f(x)=(x-1)(x-2)(x-3)(x-4)+5的导数 说明方程f′(x)=0有...
简单分析一下,详情如图所示
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(
f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),f’(x)在x=1时只有[(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)]不等于0,所以 f’(1)=(-1)*(-2)*。。。*(-9)=-362880 ...
