ABSTRACT
In discussing the variable separable solution of Boundary value Problems in cylindrical co‐ordinates for wage type region Kontorovich‐Lebedev transform has been found application. To understand the applicability of the transform some elementary properties of the modified Bessel function of the second kind, also called Macdonald function, is needed. We present below only operational proof of the results at various stages of required theorems for easy understanding of the readers in engineering and physics.
