So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错,把这个从,最大值到最小值的距离,叫做幅值,但实际上,只有它的一半,只是它和平均值的差距。
And so, again, we see a temperature increase, and we know the work, and the temperature increase, it's a constant pressure thing.
好,我们看到温度升高了,然后我们有做功量和温度的升高量,这是一个恒定压力下的值。
You've got a loop, you've got a condition and a boolean to check if he's touching the edge, and some statements to tell him to shout or to actually turn around.

PROFESSOR 2: I just want to maybe mention that in some of the reading, you'll see terms like object equality and value equality, instead of shallow equality and deep equality.
教授2:我就是想提醒下,大家阅读的时候请注意,你们会看到对象相等和值相等,而不是浅意义相等和深意义相等,教授:好,那么,这个对象。
It sets the mean to 0, for s in stocks and then for s in the stocks, it moves it, giving it the bias and the momentum, then it shows the history.
它会让平均值等于,然后,它会改变它们的值,给它一个偏向值和股价势头值,然后它就会显示历史。
Now, what did I want to do? I wanted to check membership. I want to do search. Well that's simple. Given that representation and some value, I just say gee is it there?
现在,我需要做什么?,我要做成员检查,我要做查找,这就很简单了,给了即定的表示和一些值,我只需要说喂在那儿吗?
x It says, take the name x and create a binding for that name to the value of the sub-expression and in fact to do this, to stress a point, let's do that.
它的意思是,创建了一个名字,然后创建了对于这个名字,和子表达式的值的绑定,实际上这么做,我们是为了,要强调一个点,让我们来说说这个点。
And when we're looking at the probability density graphs, it doesn't make a difference, it's okay, It has no meaning for our actual plot there, because we're squaring it, so it doesn't matter whether it's negative or positive, all that matters is the magnitude.
它的概率密度图的时候,两者没什么区别,这是可以的,它对我们画这个图,没有什么意义,因为我们是取平方,所以它的正负,无所谓,只和幅值有关,但当我们说到。
The only thing that you have to put in the function prototype, ; again, is three things; one, the name of the function; the return value; and its arguments.
你唯一要加入到函数原型中的东西,是有三个东西,一,函数的名字;,返回值,和它的参数。
Right? In other words I've got the stoichiometric coefficients in there and the values, and I'm subtracting the reactants from products -1652kJ/mol wind up with minus 1652 kilojoules per mole.
对吧?换句话说这里我用了化学,计量系数和生成热的值,从生成物中减去反应物,最后得到。
> >> David: F, c because I want to tell printf, "Use these values in those placeholders, these values in those format strings."
>,【无法辨认的声音】,>>,大卫:“f,c“因为我想告诉printf,“在那些占位符,和那个格式下打印这些值“
00 Well, it looks like it's dead on 100, which was our initial price in test two.
看上去它就固定在,这和我们测试2的初始值是一样的。
Remember when we have waves we can have positive or a negative amplitude.
记住一个波会有,正的幅值和负的幅值。
Two, the arguments or parameters, and three, is the return value.
第二个,参数和参量,还有三,是那个返回值。
Because it was one small number to one slightly smaller number.
因为这不过是一个小值,和一个稍微更小的值的区别。
One of the things we said last time was, with that set of things, the ability to give values-- sorry, to give names to values-- the ability to make decisions, the ability to loop as a function of that, the ability get things in and out, we said that that actually gave us a language we said was Turing-complete.
上次我们和以上内容一起说过,我们可以赋值--抱歉,为数值命名--可以做出判断决定-,并且据此进行循环,可以输入输出数据,我们说拥有这些功能的语言,是图灵完备的。
They might very well be storing the addresses of memory elsewhere, but we just needed them as sort of a cheat sheet, a little address card to know where the original values x and y were.
它们存储在内存的其他地方是可以的,但是我们需要一个备忘单,一个地址卡,来知道,原始的值x和y是什么。
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。
OK, but nonetheless, I want to stress we have both a value, yeah, and a type.
好,但是尽管如此,我想要强调我们有了一个值,和一种类型。
And then I could also do a Gaussian one here, with the mean of and the standard deviation of volatility divided by 2.
然后我在这里再写一个高斯分布的函数,它的浮动值的平均值和,标准偏差值都除了2。
And then I could do things like again, say, okay having done, that let me just run it here, run that, so I've now got polar point 1, and polar point 2.
然后给它们赋值半径和角度,然后我可以进行刚才的操作,也就是说,对刚才的笛卡尔坐标进行的操作,让我们来运行下它吧,运行下,现在我有一个极坐标点。
Now, this is not the nicest way to do it but it'll work. I can look at the type of the value of base and compare it to the type of an actual float and see, are they the same?
这不是最好的办法但它确实有用,我可以得到底的值的类型然后,和一个真的浮点数的类型比比,看他们是不是一样?
And then when I get to the very end, I'm going to return the bigger of with i and without i.
然后当我到最后时,我会返回包括i物品,和不包括i物品的,总价值中的较大值。
And again, our energy is going to be the same where we again only depend on the n value.
同样的能量,和以前一样,因为它,只决定于n的值。
