Question number 39 and matrices Oforder and
is a matrix of orderm x nand Bisa matrixsuch that ABT and
mxn
If and Bare matrices of the same order, then ABT -Bl A is a
skew-symmetric matrix
(b) null matrix
(c) unit matrix
(d) symmetric matrix
l, then AZ is equal to
If matrix A , where 4, =
O,ifi+j'
sin - I(rx) tan
—cot-I(zt) tan-
, then A - B is equal
