Find is the order of the matrix {:((sin theta),(cos theta),(tan theta)):}

If A is a 3xx4 matrix and B is a matrix such that both A^(T) B and BA^(T) are defined, what is the order of the matrix B?

If A is a 3 xx 4 matrix and B is a matrix such that both A^(T) B and BA^(T) are defined, what is the order of the matrix B?

For the given matrix A=[(1, 3, 5, 7), (2, 4, 6, 8), (9, 11, 13, 15)] the order of the matrix A^(T) is

If A and B are two nonzero square matrices of the same order such that the product AB=O , then

For the given matrix A=({:(1,3,5,7),(2,4,6,8),(9,11,13,15):}) the order of the matrix A is

Find the incorrect pair of statements : (i) Two matrices A and B of same order are equivalent if rho(A)=rho(B) (ii) |adj A|=|A|^(n-1) where n is the order of the matrix. (iii) A(adj A)=|A|^(2)I (iv) If A and B are two square matrices of order 3 than AB = BA.
