It is proved in this paper that the union of escaping parameter rays without.endpoints for the cosine family Sκ(z) = e^κ(e^z + e^{−z}), where κ ∈ C is a parameter, has.Hausdorff dimension 1, which implies that the ray endpoints alone have Hausdorff dimension 2. This shows that Karpi´nska’s dimension paradox occurs also in the parameter plane of the cosine family
