9^F推happy10838:我是在M群上回答你問題的那個..我覺得這題在積分上12/20 00:55

10^F→happy10838:有刁難的狀況下要你求E你直接把電場E的算是列給他看12/20 00:56

11^F→happy10838:然後注意向量..因為如果你用V的負梯度去表示的話..12/20 00:58

12^F→happy10838:算梯度的話..我不知道怎麼說..積完之後還要視情況帶12/20 01:01

13^F→happy10838:變數..似乎不會比較簡單..我也懶的重算一次了12/20 01:01

14^F→happy10838:很浪費時間的題目..12/20 01:02

15^F→happy10838:因為我算不出來..12/20 01:02

3^F推happy10838:是的..你打開之後會整理看到d1是由c1,c2組合出來的12/10 03:34

4^F→happy10838:所以還是一個常數d1=c1*cos(??)-c2*sin(??)12/10 03:36

5^F→happy10838:大概這種感覺吧12/10 03:36

6^F→happy10838:所以可以說d是一個新的常數12/10 03:37

8^F推happy10838:樓上說的沒錯..雖然是變複雜了..但如果換個角度想12/11 00:52

9^F→happy10838:本來要很辛苦的算出答案..現在答案變複雜了...12/11 00:53

10^F→happy10838:但計算起來卻變輕鬆了12/11 00:54
