当我们在二维空间画图时 b a矢量积的方向实际上是 从页面向外指出的
Or when we're drawing it in two dimensions right here, the cross product would actually pop out of the page for b cross a.
比方说这是向量a 这是向量a 这是向量b 向量b不一定要比向量a长
So let's say that's a, that's a, this is b. b doesn't always have to be longer than a.
如果这是向量a 这是向量b 垂直于向量a的向量b的分向量看起来像这样
If that's a, that's b, the component of b that is perpendicular to a is going to look like this.

So a sine theta is the magnitude of the component of vector a that is perpendicular to b.
大家看看向量b叉乘向量a是什么 我只是调换了两个向量的顺序 向量b 向量a
So let's see what happens with b cross a, so I'm just switching the order. b cross a.
发明矢量积的人 说 这仍然很模糊 因为矢量积没告诉我们 总有两个
And then the people who invented the cross product said, well, it's still ambiguous because it doesn't tell us there's always two vectors that are perpendicular to these two.
在这个例子中 这是向量a的方向 这是向量b的方向 我们计算向量b叉乘向量a
So in this example, that's the direction of a, this is the direction of b, and we're doing b cross a.

选择这条路意味着 积累起来的海量知识和智慧 向每一个个体开放 而不仅仅是单个家庭的 或者个人的积累
Choosing this option would mean that a vastly greater fund of accumulated knowledge and wisdom would become available to any one individual than would ever arise from within an individual family or an individual person on their own.
模为1的向量是单位向量
A vector is a unit vector if its norm is 1.
垂直于两个原向量的向量 一个方向向内 一个向外
One goes in, one goes out.
b有个分向量垂直于向量a
This is a, this is b.
这条向量 大家可以称之为对边向量 也就相当于这条向量
So this vector right here, and you could call it this opposite vector, that's the same thing as this vector.
