If I draw this down this this point is this year's income down here and this point here is next year's income; I'll use Y for income.
过这点画一条x轴的垂线,表示今年的收入,再画一条y轴的垂线,表示下一年的收入,我用y表示收入

Suppose f of x, y, z equals k1, that is my equation, s1 and it gives me a solution s1.
假设我的方程是这样，然后给出了一个解。
-
If its in Cartesian form I'll pass in an x and y and compute what a radius and angle is.
来得到的这个点,我都可以得到这个点的,全部的这种信息。
-
It's going to be positive in terms of its wave function or in terms of its phase anywhere where y is positive.
只要ｙ大于零它的波函数,或者说是相位为正。
-
Say, Binky, I don't think dereferencing y is a good idea because, you know, setting up the pointee is a separate step and I don't think we ever did it.
你说，Binky，我不认为不关联y是一个好主意,因为，你懂的，调定指针数据是一个单独的步骤,我不认为我们这样做了。
-
Somebody who is a math major, tell me how to solve out for the X and the Y.
哪个数学专业的同学,来告诉大家如何解出X和Y的值

So, this is several months and this logarithmic scale on the Y-axis represents antibody concentration.
这是在几个月内,这里使用的是对数刻度,Y轴代表的是抗体的浓度
-
So, in that notation, I want to ask, when is y=0?
那么这个情况下,我问你们,什么时候y=0
-
The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.
线性的威力是,一个方程，如果它是个线性方程，那么我就不用再去解他了。
-
py And finally, we can look at the 2 p y, so the highest probability is going to be along the y-axis.
最后我们来看一下，概率密度最高的是沿着ｙ轴。

If it's in polar form I passed in a radius and angle and I'll compute what the x- and y- value is.
以及半径和角度,但是现在是这样的,不管我是以哪种形式。
-
XYZ I might as well do it as x, y, z because we are talking about something that is going in three space.
我最好设成,因为我们在讨论,三维的事物。
-
So this is giving me now that template, better way of saying it, all right, a template now, for a point is x, y, radius, angle.
其他的方法来进行计算，但是这就是典型的我，要放置它们的地方，因此这就给了我一个模板。
-
This point here then is the present value of your income; it's Y today + / .
直线与x轴的交点表示收入的现值,它等于
-
What we can actually do is we could solve out for the X and for the Y.
实际上我们能够解出X和Y的值
-
chi Y This is lower case chi. I will take chi X minus chi Y.
我用chi，X减去。
-
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。
-
So here we have energy increasing on the y-axis, and you see this straight line at the bottom here is lower down on the graph, and that's the energy of a bound electron, so that's going to be a low stable energy.
这里我们看到能量沿着y轴增加，而且在这张图片上,这条直线在底部是降低的，那是一个束缚电子的能量，所以那是一个低稳态能量。
-
If x is high relative to x-bar--this is positive-- then y tends to be low relative to its mean y-bar and this is negative.
如果x比x均值要大,这个为正,而y比y均值小,这个为负
