composition是组成,function是功能,range是行列,范围,domain是域,范围,其中的意思我也不知道,根据前后意思猜测。
一、复合函数 设函数y=f(u)的定义域为Du,值域为Mu,函数u=g(x)的定义域为Dx,值域为Mx,如果Mx∩Du≠Ø,那么对于Mx∩Du内的任意一个x经过u;有唯一确定的y值与之对应,则变量x与y之间通过变量u形成的一种函数关系,这种函数称为复合函数(composite function),记为:y=f[g(x)],...

应该没关系吧, 我看看过L(x) Z(x) 只是单纯区别下不同的函数吧
(f+g)(x)是f(x)+g(x)的简便写法,也是非正规写法。在正规的表述中是不准使用的。函数(function)的定义通常分为传统定义和近代定义,函数的两个定义本质是相同的,只是叙述概念的出发点不同,传统定义是从运动变化的观点出发,而近代定义是从集合、映射的观点出发。函数的近代定义是给定一个数...
