So what we're going to do is set these two things equal to each other, put in stars here.

我们只需要令这两个表达式相等,在这里标注上*号

First one says, if you knew the force acting on any body, without going into what caused the force, then you may set that force equal the mass times acceleration of the body.

第一部分是,如果你知道作用在任一物体上的力,无论这个力的来源是什么,都可以令力等于质量乘以物体的加速度

At my maximum, I'll put a hat over it to indicate this is the argmax; at my maximum I'm going to set this thing equal to 0.

给每个最大值都标注上一个帽来,在最大值处导数方程等于0

Good, take a derivative and Set it equal to zero.

好的,求导,然后呢,令它等于0

And then set it equal to 0.

还要令导数等于0

So basically what I'm going to do here is I'm going to set my price to equal his price, minus a little bit, I'll just undercut him a little bit and by just undercutting him a little bit, I'm going to get the whole of the market and I'll make as much money as I can on those sales.

所以基本上我要做的是,设定我的价格等于他的价格,减去一点点,我的价格将仅仅比他的低一点点,并且通过比他的价格低一点点,我将占领整个市场,那些销售带给我尽可能多的钱

p2 and let's set p external equal to p2.

让外部的p等于。

At C okay, so the Nash Equilibrium here, the Nash Equilibrium is for both firms to set their prices equal to marginal cost.

价格定在C,好的,所以这里的纳什均衡,纳什均衡是两家公司都把它们的价格,设定在边际成本

We're asking the question, taking S2 as given, what S1 maximizes this expression and as the gentleman at the back said, I'm going to differentiate and then I'm going to set the thing equal to 0.

我们来讨论在S2已知的情况下,S1的最大值是多少,就像坐在后排的先生说的那样,我们要去求导然后令导数等于0

If Firm II is charging C, Then a best response for Firm 1 is to set price equal to marginal costs, and if Firm 1 is pricing at marginal cost, then conversely a best response for Firm 2 is to price at marginal cost.

如果公司2选择了C,公司1的最佳对策是,定价在边际成本,如果公司1定价在边际成本,同样的,公司2的最佳对策,也是定价在边际成本

So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.

接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数
