MCQ
If $P = \left[ {\begin{array}{*{20}{c}}
{\frac{{\sqrt 3 }}{2}}&{\frac{1}{2}}\\
{ - \frac{1}{2}}&{\frac{{\sqrt 3 }}{2}}
\end{array}} \right],\,A = \,\left[ {\begin{array}{*{20}{c}}
1&1\\
0&1
\end{array}} \right]$ and $Q=PAP^T,$ then $P^T$ $Q^{2015}$ $P$ is
{\frac{{\sqrt 3 }}{2}}&{\frac{1}{2}}\\
{ - \frac{1}{2}}&{\frac{{\sqrt 3 }}{2}}
\end{array}} \right],\,A = \,\left[ {\begin{array}{*{20}{c}}
1&1\\
0&1
\end{array}} \right]$ and $Q=PAP^T,$ then $P^T$ $Q^{2015}$ $P$ is
- A$\,\left[ {\begin{array}{*{20}{c}}
0&{2015}\\
0&0
\end{array}} \right]$ - B$\,\left[ {\begin{array}{*{20}{c}}
{2015}&0\\
1&{2015}
\end{array}} \right]$ - ✓$\left[ {\begin{array}{*{20}{c}}
1&{2015}\\
0&1
\end{array}} \right]$ - D$\left[ {\begin{array}{*{20}{c}}
{2015}&1\\
0&{2015}
\end{array}} \right]$
