摘要
文章分析了分段函数在分段点处导数值的常见计算错误,给出了函数y=f(x)在点x=x0处可导的一个充分条件,使得计算分段函数的导数值变得准确,简便.
The paper analyses the usually calculation nistakes about the devivates of the founction y=f(x) at the point x = x0, gives a sufficient condition to calculate the devivates for the founction, it makes the calculation accurate and convinent.
