5^F推sincelost:這個積分在上下限是零或是無限大時可140.112.215.64 09/20 12:26

6^F→sincelost:以用重積分的技巧積出一個數值140.112.215.64 09/20 12:27

7^F→sincelost:我也不知道能不能用積分技巧直接積140.112.215.64 09/20 12:27

4^F推sincelost:用一樓的方法設最後會求∫secθdθ210.58.42.171 08/23 23:07

5^F→sincelost:最後再代換回來要記得加常數C210.58.42.171 08/23 23:08

1^F推sincelost:答案是-pi210.58.42.171 07/04 16:23

2^F→sincelost:看到反函數就寫出定義再對恆等式積分210.58.42.171 07/04 16:23

3^F→sincelost:樓上有錯sorry 希望你有看到這篇210.58.42.171 07/05 08:53

4^F→sincelost:考慮x+sinx 在[0,π]是凹向下的遞增圖形210.58.42.171 07/05 08:53

5^F→sincelost:f(x)與他對稱於y=x 在第一象限畫個簡圖210.58.42.171 07/05 08:55

6^F→sincelost:然後就像小學算面積一樣湊出∫f(x)dx210.58.42.171 07/05 08:57

7^F→sincelost:ans: 1/2 π^2-2210.58.42.171 07/05 08:58
