Now, at the left of the origin, it turns around and starts coming to the origin and going to the right.
现在,到了原点的左边,它又转向,开始向原点运动,并到了原点右边
-
The furthest point that I recorded was 28% oil-- that puts them there-- so if they--if you wanted to, where would it be?
这图上离原点最远的点包含28%的石油-,这已经到了图上那里了-,因此如果他们。。。如果你们想的话，那一点会在哪儿？
-
when it does this, it's crossed the origin and is going to the left of the origin.
当它这样运动的时候,就经过了原点,要运动到原点左边
-
So yes, it should be zero at zero, but I made the line too thick.
它在原点处应该是零的，但我这里线画得太粗了。
-
It's as if we're back to square one with the deep, right?
这就像一切都回到了原点？
-
The violin string extends from x equals zero to x equals L, and we pluck the violin string.
弦从X轴指向原点,让x等于L，然后我们拉直那根弦。
-
And so the slope of this thing is f at the triple point, which is this point here, this is the temperature of the triple point of water, f divided by 273.16. That's the slope of that line.
除以x轴的坐标,这就是斜率，而直线,经过原点，因此斜率乘上T就得到。
-
But some origins are more equal than others because there is some natural landmark there.
但某些原点要更好用,因为它们本身也是地标
-
And x0 I'm going to reduce to 0 by choice of my origin being here.
0 等于零,因为我把原点取在这里
-
So this squared at the origin is going to be a very high probability, and it decays off as you get farther and farther away from the nucleus or from the center, and that's independent of the angle.
所以这个平方,在原点处非常高，随着离核子的距离,越来越远,它逐渐衰减，并且它和角度是没有关系的。
-
But the standard origin for everybody is the foot of the building.
不过标准的原点就是地面
-
Here, the foot of the building is what I call the origin.
比如地面,这里我以地面为原点
-
So what we do is we pick an origin, call it zero, we put some markers there to measure distance, and we say this guy is sitting at 1,2,3,4,5.
我们现在选择一个原点,称其为零点,我们做一些标记来测量距离,这个点在五个单位长度的地方
-
You can pick your origin here, some crazy spot.
你还可以把原点去在这儿,随便什么地方
-
We pick our origin to be this point here.
我们以这个点为原点
-
So, again, we're starting at zero.
同样的，原点处是零。
-
You can call that your origin.
你也可以把这里定为原点
-
Unit vector i points away from the origin in the x direction.
单位矢量 i 从原点指向 x 轴正方向
-
j points away from the origin in the y direction.
从原点指向 y 轴正方向
-
It starts from the origin and goes to this point.
它从原点出发到达这个点
-
Suppose this is the ground with some origin here.
假设这是地面,这里有个原点
-
That's the plane with some origin here.
这是一个平面,这里是原点
-
If you call that your origin, your y0 will be 0, but ground will be called -15.
如果你取楼顶为原点,你的y0就等于0,但是地面就要标记为-15
-
The x coordinate of the car is the 0, because this is my origin.
车的 x 坐标为0,因为这就是原点
-
By the way, I didn't tell you this but I think you know that I picked my origin to be here and measured y positively to be upwards and I called that 15 meters.
顺便说一下,虽然我没明确指出,但我想你们应该都知道,我把原点取在这里,并规定y的正方向朝上,我设把这里的高度为15米
