Investigating the Tachibana and Vishnevskii operators used on vvX and ccX in accordance with the almost paracontact structure in the semi-tangent bundle t(M) is the primary goal of this work. Additionally, in the almost paracontact structure, these relationships will be examined for some special vector fields. Studying the Lie derivatives of the almost paracontact structure and almost contact structure on the semi-tangent bundle t(M) with regard to vvX and HHX is the secondary goal of this paper.
