If you find an uneven pair at your table setting, it means you are going to miss a boat, plane or train. 如果你发现桌子上摆的餐具中筷子不成对的话,这就意味着你赶不上船、飞机、或是火车。
Yeah? Well, so, when we set up remember, we are setting up a double integral dy dx here So, when we do it dy dx it means we slice this region of a plane by vertical line segments. 当我们建立积分时,记住,我们将在这建立二重积分,当我们对dy,dx积分时,表示我们将平面区域用垂线分成小片。
But, generally speaking, the kinds of regions that we will be setting up things for are no more complicated or no less complicated than what we would do in the plane in polar coordinates. 其实从原理上讲,我们所做的东西,其实和我们在极坐标上做的,复杂程度差不多。
