OK, as I said, I want equality in the case of points to be, are the x- and y- coordinates the same?
好,正如我所说,我想要这个例子中的,点相等的意思是?
I said both the x- and y- coordinates are bigger, then I'm going to return something to it.
我说过如果x和y坐标,都是更大的。
For the simplest context in which one can motivate a vector and also motivate the rules for dealing with vectors, is when you look at real space, the coordinates x and y.
对于最简单的情况,我们能用矢量,以及相关的规则来处理的,是实空间,x-y 坐标系
