至于定义嘛，实际上，就是把区域分割成许多小区域，再把一点的函数值乘以那个小区域的面积，然后对乘积求和。
And the definition, actually, is we split the region into lots of tiny little pieces, we multiply the value of a function at the point times the area of a little piece and we sum that everywhere.

如果想知道是极大值还是极小值，那就只需用常识，或者直接比较各点的函数值？

现在我可以告诉你，它总是，指向更大的函数值的方向，可能半个小时后就会知道为何了。
But let me just tell you immediately to the side, which side it's pointing to it's always pointing towards higher values of a function OK, and we'll see in that maybe about half an hour.
该函数可以拥有任何名称，但必须在模块定义(DEF)文件的exports函数中用序数值1来声明它。

举例来说，如果您将一个32位的值传递给一个期望16位值的函数，而且所传递的参数值也在正确范围之内，那么这个函数就永远不会注意到多出来的字节。
For instance, if you pass a 32-bit value to a function expecting a 16-bit value, and the value is in range, the function may never notice the extra bytes.
就二重积分来讲,它是对区域里函数值求总和。
The way we actually think of the double integral is really as summing the values of a function all around this region.
这将导致关键字记录为0(但仍然返回匹配的结果)，并且函数值将是记录的唯一组成部分。
This will cause the keyword score to be zero (but the matching documents will still be returned) and the function value to be the sole component of the score.
iso - quanta是由具有相同目标函数值的点所构成的空间中的一条线。
An iso-quanta is a line in space formed by points with the same objective function value.
这意味着如果x变化,函数值不会发生一阶变化。
That means when I vary x the first order the function doesn't change.
换而言之，当约束使用新的(x 1,x2)对时，x2的变化不会引起目标函数值的变化。
In other words, a change in x2 won't change the objective function's value, given that the constraint holds for the new (x1, x2) pair.
我们说过简单的竖直区域是x在a与b之间，而y在x的函数值两个值之间。
