F x sinx是什么函数

WebSep 12, 2011 · What is f(x)? It is a different way of writing "y" in equations, but it's much more useful! WebApr 20, 2016 · f: x ↦ y means that f is a function which takes in a value x and gives out y. f: N → N means that f is a function which takes a natural number as domain and results in a natural number as the result. Because you're wrong: the → and ↦ arrows mean different things. Also, W is not the set of positive numbers: that's R +.
