6. [2 marks] A stretched string of length 1 vibrates according to the boundary-value problem Pu Pu Ət² əx² where u(0, t) = 0, u(l, t) = 0 One possible solution of this problem is '9πx 9at (A) u(x, t) = sin (STF) (C) u(r.t) = cos (E) none of (A)-(D) COS Cos 9at (0 <r<l, t> 0), (t > 0). (B) u(x, t) = sin (D) u(x, t) =COos 972 20 9xx 2l sin sin 9nt 20 9nt 20
