Abstract
In this paper the author studies the copositive approximation in C(Q) by elements of finite dimensional Chebyshev subspaces in the general case when Q is any totally ordered compact space. He studies the similarity between the behavior of the ordinary best approximation and the behavior of the copositive best approximation. At the end of this paper, the author isolates many cases at which the two behaviors are the same.
