It set a record as the fastest human-made object to ever enter the atmosphere.

VOA: special.2009.09.30

Some people like to use shallow and deep, object and value, but they're talking about the same thing, which is it the same object or is it the same, in this case, set of values, depending on what you want to define as you use it.

有些人喜欢用对象相等值相等,但是它们是同一件东西，也就是是不是同一个对象，或者是不是同样的，在这个例子中，是同样的值集合，这取决于当你使用它的时候,想要怎么来定义它。

And then to create the object, I'll simply do a set of inserts.

我将此返回做为我的集合，然后创建对象，我会一系统简单的插入操作。

So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?

这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢
