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。 - 2
Well, that's completely trivial, you would say, because it is one-half * of the mass of the Earth times the orbital speed squared. 也许你会说，这是，完全没有意义的,它等于1/2m地,轨道速度的平方。 - 3
So when we write that out, we just write sigma 1 s squared, or we can break it up into its individual parts, there's no reason we can't do that as well. 当我们把这个写出来时，我们写sigma1s的平方，或者我们可以把它拆分成每个部分，我们没有理由不能这么做。
