摘要
研究了[a,b]上的有界变差函数与[a,b]上的可微函数之间的关系,得出了有界变差函数是准可微函数;函数f(x)为准可微函数当且仅当f(x)为近似有界变差函数。
The relation between bounded variation function and differentiable function is discussed. Following from the discussion: that the bounded variation function is guasi-differentiable function and the function f(x) is guasi differentiable function iff f(x) is approximate bounded variation function.
