4^F→GanKer:回答樓上:在t<0時~不考慮"大於零或正"的部分~!但上述07/24 00:19

5^F→GanKer:的Ans t<0的上下限~還是考慮到t~負無限大~跟你所說的07/24 00:20

6^F→GanKer:有所出入~!假若像你說的~那t<0的上下限~應該是指07/24 00:21

7^F→GanKer:0~負無限大的區間才是....07/24 00:22

8^F→GanKer:回答r大:內文中的Ans:就是答案...當然還是可以繼續07/24 00:23

9^F→GanKer:算下去!!但我想須要有個人~幫我解釋一下~t>=0;t<0中07/24 00:23

10^F→GanKer:上下限的怎麼看出來的...07/24 00:24

13^F→GanKer:耶~好耶~我可以接受r大的說法!那請問一下t>=0又要怎07/24 00:29

14^F→GanKer:麼解釋呢!?07/24 00:29

17^F→GanKer:因為t>=0了~在上下限中~為什麼又會出現0~負無限大的07/24 00:31

18^F→GanKer:區間呢!?07/24 00:31

21^F→GanKer:不同的t值做討論~但這樣~t>=0又代表什麼!?07/24 00:33

23^F→GanKer:我懂了耶...畫圖會比較好懂~~謝謝你唷!!07/24 00:38
