沒找到答案 希望能對一下
以下是小弟自己算的結果 有錯還請指出 謝謝
1. 0
2. \(\displaystyle (x,y)=(2+\frac{4}{\sqrt{5}},3-\frac{2}{\sqrt{5}}) \)
3. \(\displaystyle (x,y)=(\frac{2}{9},\frac{5}{12}) \)
4 . \(\displaystyle \frac{1}{4}{
\left[ \begin{array}{ccc}
-1 & -\sqrt{3} \\
\sqrt{3}& -1
\end{array}
\right ]} \)
5.\(\displaystyle ( \frac{\sqrt{14}}{2},\frac{\sqrt{14}}{2}), ( -\frac{\sqrt{14}}{2},-\frac{\sqrt{14}}{2}) \)
6.\(\displaystyle \frac{25}{6} \)
8.\(\displaystyle \frac{1+\sqrt{3}}{2} \)
9.318
10.\(\displaystyle \frac{20}{63} \)
11.\(\displaystyle \frac{23}{2} \)
12.\(\displaystyle 0 \leq k \leq 4 \quad or \quad -\frac{1}{2} \leq k \leq 0\)
13.\((p,q)=(9,10) \)
14.4
15. \( (x,y)=(11,2) \)
感謝鋼琴老師幫指正錯誤
