We show that trigonometric Lagrange interpolating approximation with arbitrary real distinct nodes in L p space for 1 ≤ p < ∞, as that with equally spaced nodes in L p space for 1 < p < ∞ in an earlier paper by T.F. Xie and S.P. Zhou, may also be arbitrarily “bad”. This paper is a continuation of this earlier work by Xie and Zhou, but uses a different method.
