    Soln: Put 1+logx= t Differentiate on both sides wrt x, 1/x•dx=dt So int(1+logx)^2/x•dx becomes, int(t^2•dt)= t^3/3=1/3(1+logx)^3 Your final ans: 1/3(1+logx)^3 + C

    Since matrix A is skew symmetric 

    Therefore,  A' = - A    

            So,      |A'| = |-A|    

                       | A | = - |A|      (as we know that |A'|=|A| )

                    |A|+|A|=0

                         2|A|=0

                            |A|=0 

    In fact determinant of every skew symmetric matrix is always zero.
