Relation of Tangent and Secant Function and Parameter Choice

Zhang Pu-xiu

Abstract

By using the differential geometry technique,the generd parameters of extended tangent and secant funcitons of regular plane curve and regular space curve are defined to study the relation of the extended tangent and secant function and parameter transformation of a curve.The result that the extended tangent and secant function of a curve is independent with the choice of curve's parameter is obtained.
