新知探究前面我们研究了两类变化率问题：一类是物理学中的问题，涉及平均速度和瞬时速度；另一类是几何学中的问题，涉及割线斜率和切线斜率。这两类问题来自不同的学科领域，但在解决问题时，都采用了由“平均变化率”逼近“瞬时变化率”的思想方法；问题的答案也是一样的表示形式。下面我们用上述思想方法研究更一般的问题。探究1： 对于函数y=f(x) ，设自变量x从x_0变化到x_0+ ?x ，相应地，函数值y就从f(x_0)变化到f(〖x+x〗_0) 。这时， x的变化量为?x，y的变化量为?y=f(x_0+?x)-f(x_0)我们把比值?y/?x，即?y/?x=(f(x_0+?x)-f(x_0)" " )/?x叫做函数从x_0到x_0+?x的平均变化率。1．导数的概念如果当Δx→0时，平均变化率ΔyΔx无限趋近于一个确定的值，即ΔyΔx有极限，则称y＝f (x)在x＝x0处____，并把这个________叫做y＝f (x)在x＝x0处的导数(也称为__________)，记作f ′(x0)或________，即

二、典例解析例4. 用 10 000元购买某个理财产品一年.（1）若以月利率0.400%的复利计息，12个月能获得多少利息（精确到1元）？（2）若以季度复利计息，存4个季度，则当每季度利率为多少时，按季结算的利息不少于按月结算的利息（精确到10^(-5)）？分析：复利是指把前一期的利息与本金之和算作本金，再计算下一期的利息.所以若原始本金为a元，每期的利率为r ，则从第一期开始，各期的本利和a , a(1+r)，a(1+r)^2…构成等比数列.解：（1）设这笔钱存 n 个月以后的本利和组成一个数列{a_n }，则{a_n }是等比数列，首项a_1=10^4 (1+0.400%)，公比 q=1+0.400%，所以a_12=a_1 q^11 〖=10〗^4 (1+0.400%)^12≈10 490.7.所以，12个月后的利息为10 490.7-10^4≈491（元）.解：（2）设季度利率为 r ，这笔钱存 n 个季度以后的本利和组成一个数列{b_n }，则{b_n }也是一个等比数列，首项 b_1=10^4 (1+r)，公比为1+r，于是 b_4=10^4 (1+r)^4.
