1^F推profyang:只要滿足你說的那f=x-1 x<0; f=x+1 x>0即可 f'(0)不10/23 11:04

2^F→profyang:存在且導函數的左右極限都是110/23 11:05

5^F→profyang:對耶沒看清楚10/23 12:22

2^F推profyang:導函數的極限存在但函數值不存在10/21 17:52

7^F推profyang:恩3F的才對 f'+應該是右微分而不是導函數的右極限10/21 18:19

8^F→profyang:不過我2F講那句也沒錯就是XD 只是沒回答到原PO10/21 18:20

7^F推profyang:1F那個空間跟R2完全等價就這樣~10/19 13:48

[微積] 積分器出錯了?

1^F推profyang:自己微看看不就知道了= =很明顯積分器和matlab是對的10/16 11:12

2^F→profyang:喔不好意思我沒看到你自己有用微分反檢查不過你可能10/16 11:13

3^F→profyang:有算錯我看也是積分器那個才對10/16 11:14

1^F推profyang:問題就在於你常態分配那個怎麼出來的阿~XD10/16 11:17

1^F→profyang:數學系偏好這種做法物理系則偏好上一篇M大的做法10/15 23:52

4^F→profyang:數學系會說你要先證明積分微分順序可以互換10/15 23:55

5^F→profyang:但一般微積分不會證那個所以只好用分布積分證明這題10/15 23:56
