First of all, it's clear from the Pythagoras' theorem that a is the square root of ^2 + ^2.
首先,根据毕达哥拉斯定理,勾股定理在西方被称为"毕达哥拉斯定理"
So they--in other words, the insurance company--doesn't trust the insurance companies to do the calculations like I showed with the binomial theorem.
因此他们...也就是说,他们不放心让保险公司按照二项式定理,自己计算准备金要求
So there are examples in American History of elections that seem to in which the Median Voter Theorem seems to do well.
因此从美国历史上的选举案例里看,中位数选民定理非常奏效
But let's take something simple like the Pythagorean Theorem, which we all learned in high school.
不过我们还是说些简单的,比如勾股定理,我们中学里都学过的
Did he do a handstand, solve the four-color map theorem?
他会倒立,解决这个四色地图原理?
If you give me a pair of numbers, Ax and Ay, that's as good as giving me this arrow, because I can find the length of the arrow by Pythagoras' theorem.
如果给我一组数字,Ax 和 Ay,就相当于给了我这个箭头示意图,因为我可以利用毕达哥拉斯定理定理求出模长
Well there are examples in American History in which the Median Voter Theorem looks pretty good.
在美国历史上就有一个案例,此案例中中间选民定理非常奏效
And we learned how to prove the Pythagorean Theorem in Euclidean geometry, starting with the various axioms in Euclidean geometry, ba, ba-ba, ba-ba, ba-ba, ba bum.
我们都学习过,欧几里得几何中对勾股定理的证明方法,从繁杂的欧氏几何的公理开始,邦,邦邦,邦邦,邦邦
This is the "Median Voter Theorem"; thank you.
中间选民定理,谢谢你
It's called the Median Voter Theorem because the voters at the center, in this case 5 and 6, actually get to decide not just the election, but to decide therefore, what policies are put in place.
它之所以叫中间选民定理是因为,处在中间位置的选民,比如这个案例中立场5和6,实际上他们不止左右了选举结果,而且还决定了那些政策可以施行
There's another Modigliani-Miller theorem about debt, which is about debt irrelevance as well.
关于负债还有另外一个MM定律,也是讲负债不相关性的
And it turns out there's a variety of proofs of the Pythagorean Theorem.
其实有很多种证明勾股定理的方法
This proves Pythagorean Theorem.
这就证明了勾股定理
It will be about the securities market line, about the beta, about the mutual fund theorem, and it will also be about institutions that we have--about investment companies and their management.
证券市场的风险线,beta系数,共同基金定律,还有当下的一些金融机构,包括投资公司,以及他们的管理
There are mathematical theorem-proving programs.
有些程序可以证明数学定理
We'll be talking about the Modigliani-Miller Theorem and related issues in this lecture as well as something about the behavior of the stock market and its tendency to go through dramatic movements.
我们会讲到,MM定理,和与其相关的问题,还会讲到,股市行为和,股市戏剧性的运动趋势
