38F推:在浴缸做 S.M.H. ＝＝？11/21 22:14
1F→:我帶定義整理的結果，分子和你不太一樣07/13 23:55
4F→:分子我算 (ar - a^2*cosψ) 其餘不變07/13 23:56
5F→:因為外積 <-sinθ,cosθ,0> x <A-rcosθ,-rsinθ,0>07/13 23:58
6F→:然後 dl = rdθ ... 分子好像是(r^2 - ar*cosθ)才對 XD07/14 00:02
12F→:我不確定，可能要轉個彎才能求吧，直接求不定積分07/14 00:15
13F→:應該沒辦法，因為裡面有牽扯到和橢圓求周長的case07/14 00:16
