I've been solving matrix related questions and I'm confused for this one:
If A is a 5 * 5 matrix, where A^t= - A (A transpose equal to negative A) then what is the determinant for A? There are 4 options:
a) 1
b) -1
c) 2
d) 0
I thought it was zero (d) since it's an odd sized matrix but book says it's 2, how so?
