Well you know what a point is, it's got an x- and a y- coordinate, it's natural to think about those two things as belonging as a single entity.
把这两个坐标认为，是属于一个独立的实体，是理所当然的事情,因此实现这个目的的。
-
Otherwise, I'm going to get a new guess by taking g, x over g, adding them, 2 and dividing by two.
或者呢，我会有一个关于g的新猜想,就是X大于g，将二者相加，然后除以。
-
If two arrows are equal, you cannot be longer in the x direction and correspondingly short in the y direction.
如果要使两个矢量相等,那么即使 x 分量长一些,y 分量相应地小一些也是不行的
-
% Some people, the next most popular answer with 5%, which is a nice low number, wanted to put two in the 2 p x before they moved on.
下一个更多的选择占了,是一个比较低的数字，想要将两个电子在移动之前放入2px轨道,记住在我们双倍填充之前。
-
And actually, if I don't want to clobber, as we say, overwrite the value of my variable, ; I could declare another one and store the return value in Y; Y so now I have two ints in memory; X and Y, 3 one with two, one with three.
实际上，如果你不想彻底清除，像我们说的，覆盖那个变量的值，我可以申明另一个变量Y，并在Y中保存那个返回值;,现在内存中有两个int数，X和，一个的值为2，一个为。
-
If n = 1, x/n can take on only two values: 0 or 1.
当n=1时,x/n的值只可能等于0和1
-
That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.
在这一选择下,我们会发现一件非常有趣，而且极其重要的事,当你把这两点用直线连接起来，你会发现这条直线,将与x轴在某点相交。
-
Take these two equations, put an equal sign between them, replace this PR throughout with X, I'm going to have one equation and one unknown and that even the math phobics in the audience did in high school.
在这两个方程中间加个等号,将这里的Pr换成X,就会得到一个等式和一个未知数,剩下的问题,大家高中的时候就该回做了吧
-
So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.
好，为了来认识到这一点,让我们来看一个简单的小例子，在你们的课堂手册上，你可以看到我写了一个小程序,它假设我得到了，这些点中的一些，我想对它们做一些操作，例如我想把它们加到一起，那么这里的第一小片，代码的意思是，好给我两个点，我会再创建一个数组。
-
If x was even, x divided by two is going to be actually the half of x, right?
如果x是偶数的话，x除以2当然,就等于x的一半了，对不对？
-
You can see that we have two unpaired electrons in this molecule here one in the pi 2 p x star, and one in the pi 2 p y star orbital.
你们可以看到我们这个,分子力有两个未配对电子,一个在π2px星，一个在π2py星轨道。
-
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
-
So what are these two other numbers, x0 and v0 and x-not and v-not?
那么这另外两个量是多少,x0 和 v0
-
I'm passing as input the value in X, which is two.
我把那个值当输入传给X，那个值是。
-
If you want to add two vectors, you can add the arrows by the rule I gave you or just add the components of x of the two guys to get the component of the sum and likewise for the y.
如果要把两个矢量相加,你可以用我教给你们的箭头相接的方法,或者就将二者的 x 分量相加,得到和矢量的 x 分量,y 方向也是这样
-
So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.
接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数
-
Right, that divide is, if x is an integer and two is an integer, what's it going to do?
好，这个除法意思是，如果x是个整数而2也是个整数，那么会怎么操作呢？
