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 ...

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...

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...

A one-to-one function is a function in which each input value is mapped to one unique output value. In another way, no two input elements have the same output value. That is to say, each input has exactly one unique output value to which it is associated via the function. No other ...
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...
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。
