The paper discussed the characters of derivatives that it has the character of intermediate value property and it has no the character of the discontinuity points of the first kind.

No matter what the intermediate LocalDate value is, setting its dayOfWeek property to Monday always rounds "down" such that adding six days to the beginning of the month gives you the first Monday.

不管中间 LocalDate 值是多少，将其 dayOfWeek 属性设置为 Monday 总是能够四舍五入，这样的话，在每月的开始再加上 6 天就能够让您得到第一个星期一。

This paper firstly proves R-S mean value formula for integral, and USES the supplementary function for further discussing the asymptotic property of the "intermediate point".

本文首先证明了R—S积分中值公式，并利用辅助函数进一步讨论了其“中间点”的渐近性。
