Theta PI, we honor thee! From life to death, sorority!
西塔派，我们以你为荣！至死不渝，女生会！
In 1950, Sondheim graduated magna cum laude from Williams College in Williamstown, Massachusetts, where he was a member of Beta Theta Pi fraternity.
1950年，桑德海姆以优等成绩从马萨诸塞州威廉斯顿的威廉斯学院毕业。他曾是学院兄弟会[BetaTheta Pi Fraternity]的成员。
So, that's cosine theta d theta. And, well, if you do things with substitution, which is the way I do them, then you should worry about /2 the bounds for theta which will be zero to pi over two.
所以dx=cos，θdθ，如果用变量替换法来做，接下来就要考虑θ的取值范围,它是从0取到π
