inverse function 【數學】反逆函數。

inverse proportion

Considering the difference - resisting capacity of power function in classic s - box , we substitute the inverse function by better power function . we prove that these change do not influence the difference resisting capacity from the theory 其次考慮到經典s盒中冪函數的抗差分攻擊能力,我們用冪函數取代rijndael算法中s盒的求逆運算。

With the adding of appropriate conditions , we present in this note a sharper range of inverse function . this is of important to nonlinear analysis and numerical feasibility appraisal 本文通過附加適當的條件,刻劃了反函數的存在域大小,這種存在域對非線性分析中研究解的存在性、解的估計及非線性方程組求解的數值可行性都有一定的意義

The first function returns a probability value associated with a t statistic based upon the students t distribution , while the second inverse function computes the t statistic corresponding to a given alpha setting 第一個函數根據學生的t分布返回了與t統計值相關的概率值,而第二個反函數計算了與給定的alpha設置相對應的t統計值。

The global inverse function theorem is applied for the existence and uniqueness of periodical solutions to the semilinear boundary value problems . some results are improved 摘要本文運用整體反函數理論證明了一類半線性方程邊值問題周期解的存在唯一性,推廣和改進了已有的一些結果。

The properties of the and variation functions are generalized to the generalized regular variation functions and their inverse functions - ,將變化函數及其逆-變化函數的性質推廣到廣義正規變化函數及其逆函數

An integrated maximum value memory and a signal inverse function can be turned on and off at any time by a keyswitch 最大值記憶功能和信號反轉功能可以隨時通過按鍵開關來開啟或關閉。
