If A=(cos α sin α−sin α cos α),find α satisfying0<α<π2whe – InterviewSolution

1.	If A=(cos α sin α−sin α cos α),find α satisfying0<α<π2when A+AT=√2 I2;where AT is the transpose of A.
Answer» $If A = (\begin{matrix} c o s α s i n α - s i n α c o s α \end{matrix}), find α satisfying 0 < α < \frac{π}{2} when A + A^{T} = \sqrt{2} I_{2}; where A^{T} is the transpose of A .$
