There's also specialized coordinate systems, all different kinds of 'em.

还有专门的所有各种各样的。

Adam asked, what is the coordinate system used in orbits?

亚当问轨道中使用的是什么？

So in addition to identifying those planes, we make sure that the coordinate system is accurate.

所以除了识别平面，我们还要保证是精确的。

I was thinking it might be some sort of interstellar coordinate system, maybe an updated version of Hubble's law.

我猜可能是某种星际，或许是哈勃定律的升级版。

So it's almost kind of like a coordinate system, if you will.

如果你愿意的话，它几有点像。

Let's use the familiar Cartesian coordinate system with its x and y axes.

让我们使用熟悉的笛卡尔及其 x 轴和 y 轴。

And we have a coordinate system associated with that to, you know, let us know locations and how the station is moving.

我们有一与之相关的，你知道，让我们知道位置以及空间站如何移动。

Any way, to translate between vectors and sets of numbers is called a coordinate system.

无论如何 在量和数集之间转换称为。

No matter which way you face, or what coordinate system you place over the camp ground, the vector doesn't change.

无论您面方，或者在营地上放置什么，矢量都不会改变。

You can think of these two special vectors as encapsulating all of the implicit assumptions of our coordinate system.

你可以把这两特殊的量看作是中所有隐含假设的集合。

And the two special vectors I had and j hat are called the basis vectors of our standard coordinate system.

这两特殊的量和j帽叫做准的基量。

A pretty natural question to ask is how we translate between coordinate systems.

一很自然的问题是我们如何在之间转换。

So we can actually compute negative one times be one, plus two times B two, as they represented in our coordinate system.

所以我们实际上可以计算-1乘以1 加上2乘以b2 就像它们在中表示的那样。

So that, in a nutshell, is how to translate the description of individual vectors back and forth between coordinate systems.

简单地说 就是如何在之间来回转换单量的描述。

Vectors, core topics in linear algebra, like determinants and eigenvectors, seem indifferent to your choice of coordinate systems.

量 线性代数的核心主题 像行列式和特征量 似与你选择的无关。

If, E.G., jennifer describes a vector with coordinates negative one, two, what would that be in our coordinate system?

例如 jennifer描述了一为-1 2的量 它在我们的中是什么？

This is because it represents working in a coordinate system, where what happens to the basis vectors is that they get scaled during the transformation.

这是因为它表示在一中工作 基量在变换过程中会缩放。

This is something I'll go into much more detail on later, describing the exact relationship between different coordinate systems.

这是我稍后会详细讲的内容 描述不同之间的确切关。

Together they're called the basis of a coordinate system.

它们一起被称为的基。

We could have chosen different basis vectors and gotten a completely reasonable new coordinate system.

我们可以选择不同的基量得到一完全合理的新。
