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...

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. This sounds confusing, so let’s consider the following: In a one-to-one function, given any y there is only one x that...

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...

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。
