f(g(h(x))) 求导
若f''(x)存在,证明:[f(x+2h)-2f(x+h)+f(x)]/(h^2)=f''(x)
f'(x)=2.则lim[f(x-h)-f(x+2h)]/2h
Find and write in simplest form :Given f(x) = 1/x(a) f(f(b))(b) [f(x) - f(a)]/(x-a)(c) [f(x+h) - f(x)]/h
Find and write in simplest form:Given f(x) = x² :(a) f(f(b))(b) [f(x)-f(a)]/(x-a)(c) [f(x+h)-f(x)]/h
f(x+h)二阶泰勒公式f(x+h)=f(x)+(x-(x+h))f'(x)=f(x)-f'(x)h对吗?
请问lim[f(x-h)-f(x)]/-h 是等于f'(x)还是-f'(x)
设f(x),g(x),h(x)属于F[x].证明[f(x),(g(x),h(x))]=([f(x),(g(x)],[f(x),h(x)])第四题
如何证明lim[f(x+h)+f(x-h)-2f(x)]=f(x) 其中h趋向0
h(x)=max{f(x),
一道数学题(英文的)!关于(The derivatives)1.Let f(x)=2x^2-x a.Using the definition f'(x)=lim [f(x+h)-f(x)]/h,compute f'(2).h→0 b.Using the definition f'(x)=lim [f(x+h)-f(x)]/h,find f'(x).h→0 c.Does the formula in part(b)yield the corr
若f(x)有二阶导数,证明f''(x)=lim(h→0)f(x+h)-2f(x)+f(x-h)/h^2.
f(x)在x=a处可导, lim(h→0) [f(a+h)-f(a-2h)]/h=
设f(x)可微 求limh→0 [f(x+2h)-f(x)]/h
设f(x)具有二阶导数f''(x),证明f''(x)=lim(f(x+h)-2f(x)+f(x-h))/h^2
导数的定义,有式:f``(x)存在,h→0,有式:[f(x+h+h)-f(x+h)]/h 是否可以根据定义得 =f`(x+h)?如题,若f(x)二阶导数存在,h趋近与0,:[f(x+h+h)-f(x+h)]/h =f`(x+h)对吗?
