The truncation error of the two-variable Chebyshev series expansions
In [1], a formula for the error bound for the truncation error of the two-variable Chebyshev series expansions was recently given. Even though the order of the error bound is correct, there was a quantitative error. Here we find the correct formula. (C) 2003 Elsevier Science Ltd. All rights reserved.
