Question
Find the distinct singular values of $A$.$$A=\left[\begin{array}{ll}1 & -2 \\2 & 1\end{array}\right]$$
Step 1
The transpose of matrix $A$ is given by: $$A^T=\left[\begin{array}{ll}1 & 2 \\-2 & 1\end{array}\right]$$ So, $A^T A$ is: $$A^T A=\left[\begin{array}{ll}1 & 2 \\-2 & 1\end{array}\right] \left[\begin{array}{ll}1 & -2 \\2 & Show more…
