Try it again. So, sure enough, changing the bias changed the price, and even changed it in the right direction.
我们再来运行一下，好了，很明显，这个偏向值改变了价格，而且方向也是对的。

What made you change?
为什么会改变学习方向了？
-
It comes from the fact that velocity is a vector and you can change your velocity vector by changing your direction.
其原理就是,速度是矢量,你可以通过改变方向来改变速度
-
You will learn in 8.02 that if you have a charged body changing direction, that constitutes an acceleration.
你们将在8。02中学到,如果一个带电体改变方向时，产生一个加速度。

The interesting thing is that through time, as political winds change, these taxes have changed and they've gone up to some very high levels in the past in the United States and other countries.
有趣的是在不同时期,如果政策方向有所转变,税率也会改变,在过去的美国和其他国家,税率曾经相当高
-
It's just how much heat is involved when we change the temperature. Now, the products have some heat capacity associated with them right, it takes a certain amount of heat if we make their temperature change, to either put it in or take it away, depending on which direction the temperature is changing.
问题就是当我们改变温度时,有多少热量发生了转移,生成物具有一定的热容,如果我们改变,它们的温度，就要输入或,提取一定的热量,这取决于温度改变的方向。

你知道加速度意味着,不是改变速度就是改变方向。
-
This particle is constantly changing its direction, but it therefore has an acceleration and the acceleration, we have shown here, is pointing towards the center.
这个质点恒定地改变它的运动方向,因此它具有加速度,而且这个加速度,我们前面也讲过了,指向圆心
-
The fact that when you go in a circle, you accelerate is what we're learning here, coming from the fact that velocity is a vector and its change can be due to change in the magnitude or change in direction.
而当你做圆周运动时你也在加速,这是我们在这里所学到的,原因就在于,速度是一个矢量,其变化可以通过改变模长,或者方向来实现
