以下程序的功能是验证下列公式是否成立:

将x取某一值时公式鹄左侧的函数值表示为f(x)，等号右侧的级数值表示为g(x)，若f(x)与g(x)的相对误差小于10-6，即认为f(x)与g(x)相等。计算g(x)时，当最后一项的绝对值小于10-10时停止累加。

f(x)与g(x)的相对误差计算公式-Features The following procedure is to verify whether the establishment of the following formula:

　The left side of the formula Hu certain value when x takes the value expressed as a function f (x), equals the right level is expressed as the value g (x), if f (x) and g (x) relative error of less than 10-6, i.e. consider f (x) and g (x) are equal. Computing g (x) is stopped when the last of the accumulation when the absolute value is less than 10-10.

f (x) and g (x) is calculated relative error
