Okay, so while not equal to, so bang equals, exclamation point equals is computer science syntax for saying not equal to, 0 while not equal to 2 which it is not, it is equal to 0.
好的，尽管不等于不是相等的反写,但惊叹号在计算机科学的语法是不等于的意思，尽管不等于2，但它是等于。

l l So what you can do for a 1 s is just take 1 minus 1 and then l is equal to 0, so you have zero radial nodes.
它等于1减去,是等于0的，所以没有节点，这和我们看到的是相符的。

-
So for the bond order we want to take 1/2 of the total number of bonding electrons, so that's going to be 4 minus anti-bonding is 4, so we end up getting a bond order that's equal to 0.
键序等于1/2乘以,总的成键电子数，也就是4，减去反键电子数，也就是4。,所以最后得到键序为0。
-
I could have used if b is equal to 0, the answer is 1, that would have also worked.
如果b等于0的话，答案是1，这种情况也能解决。
-
So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?
这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢

And the nodal plane's going to be in the x z plane, or again, anywhere where phi is going to be equal to 0, that takes us to the x z plane.
节面是ｘｚ平面，又或者说是phi等于０的地方，这就是ｘｚ面。
-
Well, this block here on the left that I came counter counter=0 up with arbitrarily sets a variable called counter equal to 0 and then it forever says that counters value 1 and then it changes the counter by 1.
大家看一下左边的这一段代码,其中有一个随便定义的变量,它会一直显示counter的值,每显示一次，counter加。

If m is equal to 0, in this case we would call it the p z orbital, z so we would have the subscript z here.
如果m等于0，这种情况下,我们叫它pz轨道，我们在这里有下标。

We're asking the question, taking S2 as given, what S1 maximizes this expression and as the gentleman at the back said, I'm going to differentiate and then I'm going to set the thing equal to 0.
我们来讨论在S2已知的情况下,S1的最大值是多少,就像坐在后排的先生说的那样,我们要去求导然后令导数等于0
-
But notice what this does. The first thing it does is, it says, let's check and make sure x is greater than or equal to 0. If it isn't, notice what's going to happen. None of that block is going to get executed, and it's going to come down here and print out a useful piece of information, which says, hey, you gave me a negative number. I don't know how to do this.
做的是和以前一样的事情,但是注释它做了什么，第一件做的事情就是,程序说，要去检查并且确信x是大于等于0的，如果不是的话，请注意会发生什么,下面的代码都不会被执行,程序会到这里来然后显示一些有用的信息,信息会说，嘿，你给了我一个负数,我不知道该怎么弄这个了。
-
And then if we think about 3 s, 0 we want to start with 3, we subtract 1, again l is equal to 0, so minus and we have two radial nodes.
我们从3开始，减去，同样的l等于，所以减去0，我们有两个节点，这应该。

What q2 makes this equal to 0 and Katie's answer is solving out the algebra here is that q2 that solves this must be a - c over b.
2为何值时这个算式等于0呢,凯特回答其实就是算出这个的解,即,q2=/b
-
We're going to differentiate with respect to q1, the thing we're trying--our control variable, the thing we're trying to maximize the thing with respect to and set it equal to 0.
对q1求导,q1是控制变量,也就是我们想要求出的最大值,令它等于0
-
What I did was I differentiated this fairly simple function with respect to q1 and since I want to find a maximum, what I'm going to do is I'm going to set this thing equal to 0.
只不过是对q1求导了,既然我们要求出最大值,只需要令导数等于0就可以了
-
Well, dq is equal to zero and dw is equal to zero dq=0 dw=0 because it's isolated.
