The very last words say that the 5 by 6 centered difference matrix is not invertible. Write down the 5 equations Cx = b. Find a combination of left sides that gives zero. What combination of b1, b2, b3, b4, b5 must be zero? (The 5 columns lie on a "4-dimensional hyperplane" in 5-dimensional space.)
