wassup:
one more thing

when v r asked to find the inverse of a matrix

for example

M= (1  5)
     (3  2)

Determinant will be -13

So, M^-1 = 1/-13(2  -5)
                        (-3  1)

v hav to leave here only or calculate further???

M^-1 = (2/-13 5/13)
           (3/13  1/-13)

u can leave it there only or continue...both re accepted and given marks acc. to the mark scheme
