| [00:04.34] | 恋の三角関数☆ |
| [00:07.64] | cosって cosって tangent！ |
| [00:10.35] | 今はできない計算も |
| [00:12.96] | 明日にはきっと出来るよね？ |
| [00:27.02] | 出逢った時から 好きでした |
| [00:31.90] | 彼女がいるのもわかっていながら |
| [00:37.24] | 気持ち伝えたなら 三角関係 |
| [00:42.65] | 私とあなたは イコールがいいの！ |
| [00:47.49] | 方程式 解けないや |
| [00:51.48] | ひとりじゃ 答えが見つからない |
| [00:57.27] | あなたの心を 解に置き換え |
| [01:03.84] | 計算！計算！また計算！ |
| [01:08.46] | 恋の三角関数☆ |
| [01:11.24] | cosって cosって tangent！ |
| [01:14.22] | 縦軸 横軸 どっちでも |
| [01:16.85] | 恋のsineに気づいてよ |
| [01:30.48] | 宿題が終わらない！ |
| [01:34.26] | 積分も微分も 得意なはずなんだけれど |
| [01:41.22] | なぜか解けない式 方程式 |
| [01:46.62] | あなたの解答 私じゃないみたい |
| [01:51.23] | Xが何か知りたい |
| [01:55.97] | Yに何を当てはめればいいの |
| [02:01.05] | sine cosine tangent 教えてよ |
| [02:07.77] | 知りたい！知りたい！もっと知りたい！ |
| [02:12.54] | 恋の三角関数☆ |
| [02:15.10] | cosって cosって tangent！ |
| [02:18.30] | integralも忘れずに |
| [02:20.75] | 答えはすぐに わかるはず |
| [02:23.42] | |
| [02:51.34] | 恋の三角関数☆ |
| [02:54.31] | cosって cosって tangent！ |
| [02:56.84] | 今は出来ない計算も |
| [02:59.81] | あなたと解けば出来るよね？ |
| [03:02.17] | 恋の三角関数☆ |
| [03:04.99] | cosって cosって tangent！ |
| [03:07.77] | きっとわかりあえるはず |
| [03:10.29] | 二人の方程式 |
| [03:12.80] | 答えはいつもあなたよ☆ |
| [03:15.57] | じゃん！ |
