  • 建立积分的绝佳练习

    See, this is actually good practice to remember how we set up triple integrals.

    youdao

  • 没有必要对积分新命名了。

    The double integral side does not even have any kind of renaming to do.

    youdao

  • 就是重积分基本定义了。

    That's the basic definition.

    youdao

  • Szdxdy积分

    We will end up with double integral on S of z dxdy.

    youdao

  • 懂得如何计算一个函数积分

    You know how to compute a double integral of a function.

    youdao

  • 等价这个区域内部积分

    That's equal to the triple integral over the region inside.

    youdao

  • 一个建立计算积分

    One is setting up and evaluating double integrals.

    youdao

  • 当然还要学习如何计算重积分

    Of course, we will have to see how to compute it.

    youdao

  • 但是我们积分

    But let's do it as a double integral.

    youdao

  • 这也就是积分意义

    That is what a double integral means.

    youdao

  • 和计算其他积分方法相同

    It's just the same way that you would compute any other triple integral.

    youdao

  • 由于我们才刚开始积分的缘故。

    That is because we are only doing double integrals so far.

    youdao

  • 说明了,可以极坐标积分

    The claim is we are able, to do double integrals in polar coordinates.

    youdao

  • 由于表面维的,所以结果积分

    Because a surface is a two-dimensional object, that will end up being a double integral.

    youdao

  • 区域R面积函数1R上积分

    The area R is the double integral over R of a function one.

    youdao

  • 我们已经学如何建立这种积分公式

    We've seen various formulas for how to set up the double integral.

    youdao

  • 至此已经得到了,用来计算积分的所有量。

    Now I have everything I need to compute my double integral.

    youdao

  • 传统积分教学问题学生空间思维不足

    The problem of traditional multiple integral is insufficient of student's space graphs thought.

    youdao

  • 总之,就是几何方法或是曲面上建立积分

    Use geometry or you need to set up for double integral of a surface.

    youdao

  • 大多数情况下,我们需要了解怎样建立积分

    But most of the time we need to learn how to set up double integrals.

    youdao

  • 实际上我们对二重积分定义并不严谨,应该怎样严格地定义

    OK, so actually, how do we define it, that's not really much of a definition yet.

    youdao

  • 重积分可以用来得到关于这个区域某些信息或者这个区域一个函数平均值等等

    We can use that to get information about maybe the region or about the average value of a function in that region and so on.

    youdao

  • 给出积分方程网格方法具体算法网格迭代算子的结构图
