Sum

For each of the following matrices, find its transpose and state whether it is symmetric, skew- symmetric or neither.

[(1, 2, -5),(2, -3, 4),(-5, 4, 9)]

#### Solution

Let A = [(1, 2, -5),(2, -3, 4),(-5, 4, 9)]

∴ AT = [(1, 2, -5),(2, -3, 4),(-5, 4, 9)]

∴ AT = A i.e., A = AT
∴ A is a symmetric matrix.
