5^F推master0101: 錄取率分子分母除了錄取未錄取外其他的條件都要03/21 21:14

6^F→master0101: 一樣03/21 21:15

7^F推master0101: 因為芬子除了錄取與否外有一個條件"男生" 所以分母03/21 21:17

8^F→master0101: 就應該是有同樣的條件的總數03/21 21:18

3^F→master0101: 是因為題目沒說最後遺產剛好全分完嗎?11/13 14:20

4^F→master0101: 不過1位小孩是有可能的 1位小孩遺產100萬11/13 14:20

5^F→master0101: 題目沒說超過一位小孩但我算法已經假設超過一位了11/13 14:21

12^F推master0101: (x+y)^4-(x-y)^4=09/13 09:46

13^F→master0101: [(x+y)^2+(x-y)^2][(x+y)^2-(x-y)^2]=09/13 09:46

14^F→master0101: [(x^2+2xy+y^2)-(x^2-2xy+y^2)][(x^2+2xy+y^2)-09/13 09:48

15^F→master0101: (x^2-2xy+y^2)]=09/13 09:48

17^F→master0101: (x^2-2xy+y^2)]=09/13 09:48

16^F→master0101: [(x^2+2xy+y^2)+(x^2-2xy+y^2)][(x^2+2xy+y^2)-09/13 09:48

18^F→master0101: (2x^2+2y^2)(4xy)=8xy(x^2+y^2)09/13 09:49

9^F推master0101: sin(A+B)/cos(A-B)=09/06 10:58

10^F→master0101: (tan(A)+tan(B))/(1+tan(A)*tan(B))09/06 10:58

11^F→master0101: tan(A+B)=k=09/06 10:59

12^F→master0101: (tan(A)+tan(B))/(1-tan(A)*tan(B))09/06 10:59

13^F推master0101: 然後就沒想法了09/06 11:01
