    linearly independent

    Let A and B be subset of  R and consider the list
    L : x_A,x_B,x_a_(_i_n_t_e_r_s_e_t_c_t_i_o_n_)_b,
    of vectors in F(R)

    (a) Show that if the condition A(∩)B is not = ∅ and A is not a subset of B and B is not a subset of A

    Show that it is independent.

    Pls help.
