导数是高等数学中的一个重要概念,讨论了一种不同于目前多数教材中介绍导数概念的方法,以无穷小量为切入点,一步步过渡到导数的概念等,揭示了导数概念的本质,强化了学生对这一概念的理解。
补充资料：无穷小量
| 无穷小量 infinitesimal 以数零为极限的变量。确切地说，当自变量x无限接近x0(或x的绝对值无限增大)时，函数值f(x)与零无限接近，即  f(x)＝0(或 f(x)＝0)，则称f(x)为当x→x0(或x→∞)时的无穷小量。例如，f(x)＝(x－1)2是当x→1时的无穷小量，f(n)＝ 是当n→∞时的无穷小量，f(x)＝sinx是当x→0时的无穷小量。特别要指出的是，切不可把很小的数与无穷小量混为一谈。 |
