He used a computer, but you can also calculate pi at home with some needles and a sheet of lined paper.
当然，贝拉德要求助于电脑，不过你也可以用最简单的办法在自家客厅计算圆周率，所用材料只是几根针和一张横格纸。
From just these three simple examples, you can see that gnuplot understands PI and has a rich and natural vocabulary of mathematical functions.
从刚才这三个简单的例子，您可以看到gnuplot能够理解pi并具有丰富的自带数学函数词汇表。
LEHRER: How were you able to recite from memory the first 22, 514 Numbers of Pi?
Lehrer：你是如何能背诵圆周率小数点后22514位数的？
So the angular velocity omega, T which is two pi divided by T... 5 If you take two pi and divide it by 2.5, 5 it just comes out to be roughly 2.5.
因此角速度，2π除以。,如果你用2π除以2。,大概结果就是2。
You expect your child to know as many digits of PI as their age.
你希望你的孩子能记住的圆周率位数越多越好。
If you want to get the value of Pi to 10 digits of precision, the code in Listing 3 will put that value into the StringBuilder and print the output.
如果希望得到精度为10位数字的pi值，清单3中的代码会将这个值放到StringBuilder中并打印输出。
And if you ask the fans of pi why, a startling number of them will come back with the same question: "Why climb Mount Everest?"
如果你问π粉丝为什么，绝大多数人会回问你同样的问题：“为什么要爬珠穆朗玛呢？”
Kepler's Third Law, which you derived on your exam as well as on an assignment: r1 the period squared equals four pi squared times r1 plus r2 to the power three.
开普勒第三定律，就是你们在考试中和,作业中推导出的：,周期的平方等于，4π的平方乘以1,加上r2的三次方。
You start with the square of an electron's charge, divide it by the speed of light and Planck's constant, then multiply the whole lot by two PI.
一开始将电子电荷平方，再除以光速和普朗克常数，然后将总数乘以2个圆周率。
For example, you can set the xrange also: plot [-pi: PI] sin (x).
例如，还可以设置xrange：plot [-pi：pi]sin (x)。
The period, which is 2 pi times the square root of l over g, if you substitute in your length of 5.1 meters, you will find 4.57 seconds.
周期，等于2π,乘以l/g的平方根，如果把长度为5。1米,代入，会得到4。57秒。
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
You take two pi times the square root 85 of R over d and you find 1.85.
2π乘以R/d的平方根,得到1。
Pi-nong, I will send you an old Tai-Dam song that is remake by a Thai singer.
