Now, I hope you guys know that much calculus, that when you take a derivative of a function of a function, namely v square over 2 is a function of v, and v itself is a function of t, then the rule for taking the derivative is first take the v derivative of this object, then take the d by dt of t, which is this one.
我希望你们了解更多的微积分知识,当你对复合函数求导时,也就是说v^/2是关于v的函数,而v本身是关于t的函数,求导的法则应该是,第一步是这一部分对v求导,然后v再对t求导,得到这一部分
So if you're curious this one I'm gonna kill off - because it will take a little while-- you'll find that available on the cloud if you'd like to experiment whether or not you're doing that edition or the other.
由于时间关系,我就现将其关闭,如果大家觉得好奇-,可以自己尝试一下,不管你是否选择将这个版本作为,实验内容。
