1、Well, you could call that the rate of change of theta with respect to theta with a constant.
你可以稱之為，保持a不變,θ關(guān)于θ自身的變化率。

2、So we get 2gl times the sine of theta mu k*cos 2 and the whole thing to the power one-half.
所以我們得到2gl*sinθ,θ，minus，mu，of，k，times，the，cosine，of，theta,所有項除以。

3、Theta PI, we honor thee! From life to death, sorority!
西塔派，我們以你為榮！至死不渝，女生會！

4、Well, we do that by figuring out how b depends on theta when a is fixed.
,算出了b是在a不變的情形下，它是怎樣依賴于θ？

5、Now we forced this potential energy... we forced it into being dependent on theta squared.
現(xiàn)在我們使得勢能。,我們強迫它,隨著θ的平方而變。

6、R Now, v equals omega R, R so that equals theta dot times R.
現(xiàn)在v等于ω,即等于θ點乘以。

7、This number can be larger than zero >0 if the sine theta is larger than zero.
這個數(shù)字可以大于,只要sinθ

8、With the chain rule, gives me a theta dot.
根據(jù)鏈?zhǔn)椒▌t，我得到θ點。
