other y'(pi/4)=-3

Find all solutions, y (a ), of the boundary value problem y" + 16 y = 0, y'(0) = 2, The k below is an arbitrary constant. Oy(x) = - cos(4x) + s 3 sin (4x) Oy(x) = k cos(4x) + sin(4ac) None of the options displayed. Oy(x) = 2 cos(4x) - 3 sin(4ac) The boundary value problem has no solutions. Oy(a) = > cos(4x) + k sin(4x), Oy(20) = 2cos(4x) Oy(x) - -2 cos(4x) + 3 sin(4x)
