摘要
函数在分段点的导数是微积分教学中的一个难点.剖析了学生在解涉及分段点的导数这类题目时常常会犯的一个错误,给出了函数在分段点处可导的一个充分条件,利用这一条件判断函数在分段点处的可导性比用定义判断要方便得多.
How to calculate the derivatives of separate function points is a difficulty analyzes why the students would always make mistakes in their solutions solving these condition that the derivatives of separate function points exist, which is much more definition. in calculus teaching. This paper problems, then gives a sufficient convenient to be used than the
