1F推:如果函數圖形定義為 Gr(f)={(y,x) in R^2 : x=f(y)}06/28 11:07
2F→:f(y)=0就是函數了 我想這是老師想表達的06/28 11:08
24F推:借轉數學板06/25 14:25
2F→:COOL!!! 感謝!07/21 22:24
3F→:但資料還是很少Orz07/22 19:24
8F推:小一前就背九九乘法表 是件好事也是件壞事04/07 07:35
9F→:有些小朋友背了就不想懂 另一些小朋友懂了就不想背04/07 07:35
3F→:OK謝謝06/24 16:27

16F→:就說不是中文了QQ04/18 11:55
17F→:再說 我當時就知道一除二等於二除以一了04/18 11:56
21F→:樓上上 就變成b100%啊 老師哪裡對了04/18 12:12
27F→:我修文回應喔?04/18 12:44
31F→:不一樣=.= 你自己下BB機率是多少 AAA機率又是多少04/18 12:52
34F→:我那個就是樹狀圖 只是BBS不好分支04/18 12:53
36F→:囧 我再修文04/18 12:53
42F→:AAA的機率 = A^3 = 0.5^3 != 1/1004/18 12:58
46F→:f大...你還是仔細看一下我的吧=.=04/18 13:02
47F→:或是解釋看看為什麼AAA會是1/1004/18 13:03
51F→:filenwind大的也不對 應該是(C4取3+C4取4)/2^404/18 13:05
52F→:filenwind大的取法會取到BBAAA 這樣A不算贏04/18 13:06
54F→:fallen0415大我出另一題給你 A隊要連贏3場才贏 B隊贏一04/18 13:06
55F→:場就算贏 請問A隊最後獲勝機率?04/18 13:07
56F→:我沒有問題 所以我不用貼數學板=.=04/18 13:07
57F→:(續前題) 若不設任何規則 A隊連贏三場的機率為?04/18 13:08
59F→:你會發現你的兩個答案不一樣 但事實上它們是一樣的04/18 13:08
