你可以观察不同的点-，我用从1983年到2006年的数据-，代入我们刚教授的等式，进行了计算。

You can see the different points — I've calculated this using data from 1983 until 2006 — and I computed all of the inputs to those equations that we just saw.

现在，在这个点上代入值。

OK, so, now let's just plug in some values at this point.

所以，方程就是4x+2y-2z=某个值，某个值就是，我们应该代入这个点。

OK, so the equation is, well, 4x+2y-2z equals something, where something is, well, we should just plug in that point.

if I say a particle's location is i times t^2 plus j times 9t^3, for every value of time, you can put the numbers in and you can find the velocity by just taking derivatives.

一个质点的位置,i ? t^2 + j ? 9t^3,在每一个时间点,你可以把数值代入,并通过求导得到速度
