It fears that this time the dice may be weighted against its more costly but "better value" A330-based tanker in favour of Boeing's smaller 767 derivative.

空客害怕这一次可能有黑箱操作，导致不会选择虽然更贵但“更物有所值”的基于A330的空中加油机，而会选择较小的基于波音767的衍生机型。

And when I change x, z changes, and the slope of that is going to be the derivative with respect to x.

这样x为自变量，z为因变量,这条曲线的斜率就是关于x的导数。

Even though we started with a single vector, which is the position vector, we're now finding out that its derivative has to be a vector and the derivative of the derivative is also a vector.

即使我们从单个矢量出发,即位移矢量,我们现在也能得出它的导数是矢量,而且导数的导数也是一个矢量

At any point on the graph you can take the derivative, which will be tangent to the curve at each point, and its numerical value will be what you can call the instantaneous velocity of that point and you can take the derivative over the derivative and call it the acceleration.

在图上的任意一点,你可以进行求导,得到曲线上每一点的切线斜率,所得到的数值,即为该点处的瞬时速度,然后你再求一次导,得出它的加速度

If you took the derivative of this, you will get the velocity at time t, it would be: v=v0+at.

如果你对它求导,你就可以知道 t 时刻的速度,即,v=v0+at
