So, the two most elementary ideas you learn are what is the average velocity of an object, as then ordered by the symbol v-bar.
你们学过的两个最基本的概念是,物体的平均速度,用"v拔"表示
Then, to find the meaning of b, we take one derivative of this, dx/dt, that's velocity as a function of time, and if you took the derivative of this guy, you will find as at+b. That's the velocity of the object.
接下来,为了弄清b的含义,我们取它的一阶导数,dx/dt,得到速度作为时间的函数,如果你对它求导的话,你会得到at+b,这就是物体的速度
