1·And so what we will see is you may have heard of Lagrange multipliers.
接下来要讲到的，就是你们可能听说过的拉格朗日乘数法。
2·Expect one about a min/max problem, something about Lagrange multipliers, something about the chain rule and something about constrained partial derivatives.
有一个极值问题，也有关于拉格朗日乘数法的，链式法则也会有的,约束条件下偏导数当然不会漏掉。
3·So, then we've seen the method of Lagrange multipliers.
我们就此学过拉格朗日乘数法的。
4·More important, the scale of the global slump means that historical multipliers may not mean very much.
更重要的是，这次全球萧条的规模史无前例，意味着按历史经验得出的乘数或许意义不大。
5·Fiscal multipliers will probably be lower in heavily indebted economies than in prudent ones.
与谨慎的经济负债相比财政乘数将可能在更高的经济负债中变得较低。
