You cannot have two vectors equal without exactly the same x component, exactly the same y component.

你不能说两个矢量相等,如果它们的 x 分量不完全相同,或者 y 分量不完全相同

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？

So who the sender is, so maybe you could keep track of just who your most frequent correspondents are and if you keep seeing the same personfrom person X or person Y coming into your inbox and clearlyI like having a dialog with these people or have to for work, that might in fact bubble up in your inbox.

谁是发送者，你可能会保留最近跟你联系最频繁的人,如果你发现某某人频繁发送邮件给你,这说明你喜欢和这些人保持联系,可能因工作的原因必须保持联系,那么该邮件就有可能，上升到你邮件的最上方。

If I do that, I would like to call the coordinate y, then I will write the same thing.

如果是那种情形,我会把坐标记为y,然后写出一样的式子

If they tend to move together, when x is high and y is high together at the same time, then the covariance will tend to be a positive number.

如果x和y同向变动,当x值和y值同时都很大,协方差的结果将会是一个正值

So they're the same shape, this is the shape of the orbital or the shape of the wave function, and we can call this either 2 p x a being combined with 2 p x b, or we could say since it's the same shape, it's 2 p y a being combined with 2 p y b.

它们形状是一样的，这是轨道的形状或者波函数的形状，我们叫它2pxa和2pxb结合，或者我们说因为它们的形状是一样的，它是2pya和2pyb结合。

Add the same thing to the y-values, squared, take the square root.

的差的平方，然后加起来开平方。

I'm going to say, gee, p2 is the x value the same in both of them, and if it is, and the y value's the same, then this is the same point, I'm going to return true.

这样的数据对象，我会把它们命名为p1和,我会去查看，看看两个对象中，的x值是不是相同，如果相同的话，就去查看y值是否相同。

Now, y points to the same place as X. So, wait now y is fixed.

现在，y和x指向同一东西，所以现在y被修正了。

Then I do the same thing on line two and I declare something called "y."

然后我在第二行做了同样的事情,我声明了“y“

Can you fix it so that y points to the same pointee as X?

你能使y指向x所指向的数据么？

You go back to the same x-y plane; here is some vector A.

回到刚才的 x-y 平面上,这是某个矢量 A

y are these the same?

坐标赋值为4，OK，，now，I，want，to，say，好，现在我想看看？

pxa So what happens when we add a 2 p a and we subtract from it a 2 p x b, or the same with a 2 p y a subtracting a 2 p y b, is that we're actually going to cancel out the wave function in the center, so we now have 2 nodal planes.

当我们用,减去2pxb时，或者是2pya减去2pyb时，我们会消去,中间的波函数，所以现在我们有两个节面。
