Determining the Asymptotic Form of The Eigenfunctions of The Sturm-Liouville Problem in a Particular Case

In this paper we consider the regular Sturm-Liouville problem-py+(q-r(gama)y=0,On the interval [0,(pi)], with initial conditionsy1(0)=(pi) and y1(0)=0 and y2(0)=0 and y2(0)=(pi)where p and r are positive functions, we will determine the asymptotics form of theeigenfunctions of Sturm-Liouville problem in a particular case.
