In a one-to-one function, given any y there is only one x that can be paired with the given y. A graph of a function can also be used to determine whether a function is one-to-one using the horizontal line test: If each horizontal line crosses the graph of a function at no...

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。

Functions can map elements from the domain to the codomain in many ways. A function may "hit" every element in the codomain, or it may "miss" some. It may assign more than one x to a y or it may assign exactly one x to each y. We will understand our function better if we know...
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...
线性代数里 one-to-one什么意思?说是同一个矩阵 可以是one-to-one且ONTO 希望有人解答 答案 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...
