what we're going to do is we'll refer back to this other picture,

我们先来参考一下之前的图像
which is why I left it here.

所以我之前没有擦掉它
So, in particular,

比如说
what would be Player 1's best response if Player 2 didn't produce at all?

参与人2产量为0时1的最佳对策是什么
How do we find that?

这个怎么求解呢
Without worrying about the economics of it a second,

不需要考虑经济学的理论
how would we find that just as a math exercise?

用数学的方法怎么来求解啊
So suppose Player 2 doesn't produce at all.

假如参与人2产量为0
What is Player 1's best response? Someone read it off for me.

谁来说一下参与人1最佳对策是什么
Why don't we cold call somebody out, you can?

我随便找一个吧就你回答吧
a - c over 2b.

是(a-c)/2b
All right, so shout that out.

没错大点声说
