Page 16:
The last equation on the page, for the Lagrange polynomials,
should be divided by (N+1).
 Page 59:
All the summations on this page should be up to N, not (N1),

Page 144:
In example 8.9, the polynomial of degree (N1) satisfies
the equation at the collocation points j=1, . . ., N1 and satisfies the
boundary condition.

Page 155:
The summation at the bottom of the page should be n > N/2.

Page 189:
The eigenvalues for the FourierGalerkin
first derivative operator are all imaginary and should be
(i N/2, . . . , i, 0 , i, . . . , i N/2).
