one-to-one,意思是"一对一"通常指一对一映射,或"一一对应映射."ONTO意思"到上" ,通常指满映射或满射,INTO意思"到内" ,通常指单射或一对一映射,设f是A到B的函数,如果对任意属于B的y,均存在属于A的x,使得f(x)=y,则称f... 分析总结。 onto意思到上通常指满映射或满射into意思到内通常指单射或一对...
内容提示: ONE-TO-ONE AND ONTO FUNCTIONS The concept of one-to-one functions is necessary to understand the concept of inverse functions. One-to-One Functions If a function has no two ordered pairs with different first coordinates and the same second coordinate, then the function is called ...

onto和one to one的区别：意思不同。onto 英 [ˈɒntə] 美 [ˈɑːntə]prep.(与动词连用，表示朝某处或某位置运动）向，朝；朝向，面向（某个方向）。one to one 英 [ˌwʌn tə ˈwʌn] 美 [ˌwʌn t...
Section 3: One-to-one, Onto, and Inverse Functions• In this section, we will look at three special classes of functions and see how their properties lead us to the theory of counting. • So far, we have the general notion of a function :X → Y, but in terms of the comparative...
onto 是漫射 台版翻译叫映成函数 映成函数(onto function)：设f：A→B，如果f(A)=B，则f是映成函数。换言之，B理的每一分子都出现作A的像，那f是映成函数。
6. In order for a function to be invertible it needs to be one-to-one and onto. The function y= arcsinr (or y= sin r) is the inverse of the sine function y= sin.r. The problem is that the sine function is not one-to-one. In order to find the inverse we must restrict the...
