数值计算课后习题答案-

习题一解答1．取3.14，3.15，227，355113作为π的近似值，求各自的绝对误差，相对误差和有效数字的位数。

分析：求绝对误差的方法是按定义直接计算。

求相对误差的一般方法是先求出绝对误差再按定义式计算。

注意，不应先求相对误差再求绝对误差。

有效数字位数可以根据定义来求，即先由绝对误差确定近似数的绝对误差不超过那一位的半个单位，再确定有效数的末位是哪一位，进一步确定有效数字和有效数位。

有了定理2后，可以根据定理2更规范地解答。

根据定理2，首先要将数值转化为科学记数形式，然后解答。

解：（1）绝对误差:e(x)=π－3.14＝3.14159265…－3.14＝0.00159…≈0.0016。

相对误差：3()0.0016()0.51103.14r e x e x x -==≈⨯有效数字：因为π＝3.14159265…=0.314159265…×10，3.14＝0.314×10，m=1。

而π－3.14＝3.14159265…－3.14＝0.00159…所以│π－3.14│＝0.00159…≤0.005=0.5×10－2＝21311101022--⨯=⨯所以，3.14作为π的近似值有3个有效数字。

（2）绝对误差:e(x)=π－3.15＝3.14159265…－3.14＝－0.008407…≈－0.0085。

相对误差：2()0.0085()0.27103.15r e x e x x --==≈-⨯有效数字：因为π＝3.14159265…=0.314159265…×10，3.15＝0.315×10，m=1。

而π－3.15＝3.14159265…－3.15＝－0.008407…所以│π－3.15│＝0.008407……≤0.05=0.5×10－1＝11211101022--⨯=⨯所以，3.15作为π的近似值有2个有效数字。

（3）绝对误差:22() 3.141592653.1428571430.0012644930.00137e x π=-=-=-≈-相对误差：3()0.0013()0.4110227r e x e x x--==≈-⨯有效数字：因为π＝3.14159265…=0.314159265…×10， 223.1428571430.3142857143107==⨯，m=1。
