英文高数概念题
1.Let f:Rn --> Rk be a given function,we say that f is differentiable at A if .
2.Carefully state what it means for a function f:Rn --> Rk to be differentiable.
请用英文回答,
Rn,Rk指的是n维,k维的向量集合,不存在左导数=右导数

1定义f Rn~Rk 是给定的函数,那么什么时候 f可微
答案:f(A) exist and f'(A-)=f'(A+).(fA存在,且A的左倒数等于右倒数)
答案:It means when d(Rn)~0,d(Rk)~0 and f is continuous at its given areas.(当Rn的变化量趋近于0 时,Rk的变化量趋近于0 ,且f在定义域内为连续函数.这里的“~”表示趋向于,我手机打不出来.)
我用手机打的,不容易啊,分就给我吧,
问题在2.汉语意思如下:
仔细阐述对于一个函数f可导意味着什么?
答:函数在可导处必连续。
