## FAQs on Symmetric, Anti- symmetric, Orthogonal Matrices Video Lecture - Mathematical Methods - Physics

 1. What is a symmetric matrix?
Ans. A symmetric matrix is a square matrix that is equal to its transpose. In other words, the elements of a symmetric matrix are symmetric with respect to the main diagonal.
 2. What is an anti-symmetric matrix?
Ans. An anti-symmetric matrix is a square matrix that is equal to the negative of its transpose. In other words, the elements of an anti-symmetric matrix satisfy the condition A^T = -A.
 3. What is an orthogonal matrix?
Ans. An orthogonal matrix is a square matrix where the transpose of the matrix is equal to its inverse. This means that for an orthogonal matrix A, A^T * A = I, where I is the identity matrix.
 4. How can symmetric matrices be identified?
Ans. Symmetric matrices can be identified by checking if the matrix is equal to its transpose. If A = A^T, then the matrix is symmetric.
 5. Can a matrix be both symmetric and orthogonal at the same time?
Ans. Yes, a matrix can be both symmetric and orthogonal if it satisfies the conditions of being equal to its transpose and having its transpose be equal to its inverse.
