  1. V = span(S), where S = {(1, i, 0), (1 - i, 2, 4i)}, and x = (3 + i, 4i, -4)
  2.  
  3. (1)Apply the Gram Schmidt process to the given subset S of
  4. the inner product space V to obtain an orthogonal basis for span(S).
  5. (2)Normalize the vectors in this basis to obtain an orthonormal basis B for span(S).
  6. (3)Compute the Fourier coefficients of the given vector relative to 0 by solving the
  7. system of equations a1u1 + a2u2 + a3u3 = x, where u123 are the vectors of basis B
  8. (4)Compute the Fourier coefficients directly by ai = <x, ui>
  9.  
  10. B = { (1/(2^.5))(1, i, 0), (1/(2(17^.5)))(1 + i, 1 - i, 4i)}
  11.  
  12. (7 + i)/(2^.5) , (17^.5)i
