Let's plot droplet velocity as a function of looking at the number that have this velocity 0 with the zero being in the center here.
我们将液滴的速度设定为,观察那些数字作用,在中心的地方,速度为。
That's correct. So her answer was, if it was a full parabola, then we know it would've been at the ground before I set my clock to 0.
她说,如果运动轨迹为一条完整的抛物线,那么它在我们所设定的零时刻之前,就已经落地了
What I want this class to be is a class where at least sometimes, like on this homework assignment, I set up a model for you, set up the story for you, and then you have to actually figure out how do I set this up properly and how do I solve it out?
我希望这个课程是至少在某些时候,就像这次家庭作业,我为你们设定一个模型,设定故事情节,然后由你们自己实际操作,如何恰当地设计并解决它
It's reasonable because it's meant TMP for temporary purposes just to call it temp or T-M-P for short, X and I can define temp as -- why don't I set it as equal to X, initially, because now that I've stored X in a separate chunk of memory, I can now change its value and then I can say Y gets, not X, but temp, and so now I've actually swapped these values.
这是合理的,因为它是为,暂时的目的,只要叫它Temp或简称它为,我可以定义temp为--为什么我不把它设定为等于,最初的,因为现在我把X存储在一个单独的内存块中,我现在可以改变它的值,然后我说Y等于,不是X,而是temp,所以现在我交换这些值。
What it means is if you'd release a rock at that location one second before with a certain speed that we can calculate, it would've ended up here with precisely the position and velocity it had at the beginning of our experiment.
它的意义在于,若在该处以特定速度抛出一个物体,这个速度可通过计算得到,一秒之后,物体会运动至我们设定的起点,并且速度为我们设定的初速度
This strategy set--formally, Let's just simplify it here-- let's assume that for each Firm i they can set their price anything bigger than 0 and anything less than 1, just to keep life simple.
至于策略集合,我们把它简化成,假设每个公司i能,将它们的价格设定为,大于0并且小于1,仅仅为了简化处理
They all set a standard.
他们都为我们设定了标准。
